Figured it would be a good idea to collect known issues in one place:

1. Dedicated servers with mods to enable more than 15 pals per base can have pals 16+ assigned to a base deleted Source

• For the above, I would have dedicated servers with such mods hold off on 1.5.1 until players get a chance to put all their base pals back in their palbox and/or update their worldoptions.sav file with the correct max pals: Website to create a custom worldoption.sav Local run version or better yet set the max number of workers in PalWorldSettings.ini then use this tool to create a new worldoptions.sav file.
• Servers that are using a custom WorldOption.sav to increase the Base worker limit may be spared from this issue.
• "Deleted" pals may be in spheres above the vicinity of the Palbox.

2. Pre patch incubators will not work (will only accept/store small pal souls)

• Destroying and rebuilding the incubator seems to fix this.

3. The Pal Info mod (and likely any mod that shows Pal info) conflicts with 2.0.6 and as such should be disabled until the mod author can update the mod for 2.0.6
4. Players with UE4SS installed get a blank screen when trying to start the game and log in.

• Go to Palworld/Binaries/Win64/Mods/ edit mods.txt to change BPModLoaderMod from 1 to 0.
• Note, UE4SS Blueprint type mods will not work with the fix above but at least you'll be able to log into the game Credit

5. Dedicated servers may fail to launch

• The server executables have new names.
• Make sure your scripts point to the new server names (old ones had -test at the end, new ones are -release I believe)
• If you're using any firewall rules that point to a specific name for the dedicated server process, it'll need to be updated to the new binary name.

Increase Pal Storage

0. Shut down the server

1. Make a backup of your local or server save file (level.sav) and the player files just in case.

2. Download the python utility below:

https://github.com/touchfluffytails/Palworld-Palbox-Slot-Injector

3. Download "PalWorld Save Tools"

https://github.com/cheahjs/palworld-save-tools/

4. Run the command on the save file (you did back it up, right?)

inject_box_slots.cmd

(select 17-64 pages, 30 pals per page)

5. Start the server back up

And that's it, you can skip the rest of the listed steps in the tool pages, why?

Just running the tool against your save file, you will be able to see and interact with the additional storage in the Pal and Black Market merchant "sell pal" screen.

The extra steps that are listed in the tool's page (UE4SS, injector, download and install the "Bigger and Better Palbox" mod on the server and for each client, etc will only do two things if you get them all to work:

1. The extra slots (pages 17+) will be visible in the PalBox
2. New players will automatically have their save data adjusted to give them the extra slots.

If you just want the extra storage with the caveat that it can only be seen, reorganized and pals on pages 17+ moved to pages 1-16 at a pal or black market merchant, then you only need my 5 steps above and it only needs to be done once on the server (and again if any new players join to give them the extra slots).

No additional mods needed and the players connecting to the server won't have to do anything else.

I submitted a request in the official PocketPair PalWorld discord "ideas-and-wishes" channel to implement the UI from the pal vendors (when selling) in the Condenser. If they implement that idea, then with just the modified save file you would be able to condense the pals you have on pages 17-64 without visiting a Pal Merchant to move them to pages 1-16 first.

Adding bases

This one is simple:

1. Download "Duck's Progressive Bases"

https://www.curseforge.com/palworld/patch-pak-mods/ducks-progressive-bases/files/5059584

2. On the Server create a "~mods" folder (no quotes) in the Pal/Content/Paks folder

3. Put the pak file from zip you downloaded in that folder

4. Do the same for each client that will connect to the server.

5. Restart the server!

Other mods

Pretty much any mod that comes as a .pak and does not need UE4SS can be installed easily on a Linux Pal server.

Server Only Mods:

These mods only need to be installed on the server (change backend stuff like loot drops)

• Gear Progression

Client Only Mods

These change UI items that don't require coordination with the server

• Pal IVs (shows the pal inherent stats) Requires UE4SS installed

Server and Client Mods

These make changes that the server has to "allow" and the clients have to be aware of:

• Duck's Progressive bases (if installed on the server only, the players won't see the option to build more than 3 bases).

I'll add more to this list as I test out and find more mods.
