Same here, cannot login since the midseason patch hit yesterday. FenrisDebug are full of these error messages:
E 2024.11.20 11:25:21.722059 228 [Sigma] [tact] [:0]: Invalid read offset requested for file 9ecc0da9c79e3d32a800000000000000. Offset: 1310720 FileSize: 252
Before the patch there was no problem.
