Battle.net app keeps initializing and reclaiming

Battle.net app keeps initializing and reclaiming disc space for games.
I found that this happens only when the games are located on a drive with exFAT file system. Moving the games to a drive with NTFS file system fixes the problem. Please check and fix, because this is making me crazy.

can confirm this is also happening on my games.

this is still happening but i fixed it by making a NTFS partition on my SSD and moving battle.net games there (was exFAT before)
