I only found a DL_cache folder in the WoWs folder and backed up the 7z files found in there just in case. If there is another cache folder please tell me where I can find it within the WoWs folder. Modpack itself is installed to steamdir\SteamApps\common\World of Warships
The AL icons for captain skills also went completely missing. I reinstalled the latest version as instructed and it didn't help.
