Update A modpack update fixed it Apparently needed a new version of XVM.
Todays patch was to fix some technical issues.
- Fixed the issue with the display of Battle Results after the end of a special battle, if there was no information about the enemy.
- Fixed the issue where vehicles could sometimes disappear from view in Arcade Aim in the Spectator mode.
When maintenance has completed please restart World of Tanks using the launcher file (WOTLauncher.exe) and ensure your game client updates properly.
If automatic updating has been enabled in the launcher settings, make sure that the client has finished updating.
Maintenance will begin at 02:00 Pacific Time (09:00 UTC) and will last approximately one hour.
During maintenance, the World of Tanks servers will be unavailable.
I have had to start game in SAFE MODE to be able to mount and dismount equipment.It seems will need a Mod Pack update to be able to run Aslains again.
