All the information is still weird and confusing.
BAT is not installed on this server. This is an empty modifiable server. there’s nothing on it but a couple of cards
I received 5 logfiles and two screenshots via PM from you.
All of these show a custom modded 4.12.2 server installation.
Nothing like an "empty modifiable" server, rather an attempt to create a custom mod based on BAT.
But you've made a lot of mistakes when creating that custom modpack.
For instance, the whole BAT00 folder is missing.
Furthermore, the "logs.lst" file clearly shows that your server wants to load all BAT planes from air.ini, but the java classes are missing.
Last but not least, all other logs show a custom install of the P-47 modpack on top, but again with missing files (this time flightmodels).
- BAT 3.7 has never worked like that.
I have no idea why you claim that this sort of thing would have worked with 3.7 and got broken with 3.8, but truth being told, that whole thing you've created there doesn't work with anything and it never did.
It's simply messed up beyond repair. - You need to install BAT on the DServer in order to play BAT with a DServer.
If you do not have BAT installed on the DServer, you cannot play BAT on the DServer.
I mean... I can't play Ultrapack on a Stock 4.10.1 DServer either and honestly, I thought that'd be obvious.
