Version 9.3.0 #1
I removed ALL signal, flag and camo mods and logged in fine. Added each back in singularly and failed to log in each time. Therefore I suspect it's a conflict with WG's updated UI in respect to signals and camos and the flags are linked into that somewhere.
Hope this helps.
Initially logged in fine to NA server without mods. Downloaded latest modpack but was unable to login. Login froze/suspended/halted at the first splash screen. Instead of WG's new seasonal splash screen the modpack reverted it to my selected/default splash screen.
UPDATE - I disabled all Loading Screen mods, didn't realise I had some enabled, and can now login.
[EDITED TITLE TO REFLECT THE ACTUAL ISSUE]
Since updating to v.8.9.0_06 instead of ships' names I'm just getting white blocks instead of letters as an OTM. I removed my OTM (Badofest HP + Nick) mod but the problem persisted.
Also I don't think that a mod would have access to what flags, upgrades or commander skills the enemy ship would be using that would alter the base numbers so any mod wouldn't be that useful and if it did then, yeah, would be a totally unfair advantage.
