Some people on my server are getting this bug that seems pretty common in 20.4

ERR NCSimple_Serializer (ch=0):

EXC Memory stream is not expandable

which makes the game unplayable. We want to roll back the server to 20.3 but I don't see any options for this in the settings. Is there a way to do it manually?

This host only supports the versions of the released games that the actual publishers of the game supports. In the case of 7 Days to Die, that would be the latest stable, and the latest experimental releases.

The error you are experiencing is a bug with the drones. Clicking the word bug should take you to the forum to read more. Below is the fix mentioned, and we have tested that this does work.

I solved this by copying my player profile to a single player world, start the single player game, exit the single player game, copying the player profile back to the dedicated server. There seems to be a limit of 2 mb on player profiles for dedicated servers, and it can't get bigger than that. This limit doesn't seem to exist for single player worlds. Something with the drone is loading up the player profile with info that it shouldn't be. Once you load into a single player world, it cleans the erroring data and brings your player profile down to the size it should be and then you can load it on the server.

 

For now it seems we just need to put the drones in a box until TFP can fix the issue.
