Some mods generate a red circle when playing multiplayer. On investigation, those with red circles have a different hash number between the windows client and the linux server. This has appeared since the 1.60 update. I'm using the same mods on both client and server with the same load order. This set up worked before version 1.60.
Have sent the to support and have tried lower case on the mods and removing start up parameters which hasn't helped. Now submitting again as requested.
Install the same mods on server and client then play multiplayer.
Example:
Server side (hash number 11fdd19c)
12:51:09 SFP: Objects | @sfp_objects | false | GAME DIR | da39a3ee5e6b4b0d3255bfef95601890afd80709 | 11fdd19c | /home/steam/steamcmd/arma3/@sfp_objects
Same mod on the client side (running win 10) (hash number 191a8d4)
8:57:49 SFP: Objects | @sfp_objects | false | GAME DIR | 18f6d7c289a8e0edb9ede07747ddab07fe9f4ea1 | 191a8d4 | D:\Program Files (x86)\Steam\steamapps\common\Arma 3\@sfp_objects
