PC Patch 3.0.2 - Discussion Megathread

Can anyone summarize whats the status after 3.0.2?

I am running a dedicated server with several (few) mods. No total conversions, mainly quality of life (see: [EU] New casual player oriented server - PVE-C Siptah)

Since 3.0.2 I can’t connect anymore; my client will state that a PAK file is corrupted and refuse to start the game after connecting to the server.

Do we need mods to be updated? How can I find out which mod it is? All my mods have now been updated so they use the 3.0 devkit (I use G-Portal and none of the mods are shown as outdated / all newer than sept 1st).

Whats wrong? How can I fix it?!
