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]
