[2021] Lots of game crashes in chaos wastes

Thanks for the report!

In the logs I can see a common occurence of

..._extensions/default_player_unit/buffs/buff_templates.lua:3228: attempt to get length of local 'server_buff_ids' (a nil value)<>

This is a known issue and will be remedied in our next hotfix.

Sorry for any inconvenience!
