When i added HBS Batletech to lutris in started almost instantly, but every time i ran it lutris was taking more and more time to “prepare to launch Batletech”. I tried recreating lutris entry (pointing to the same wineprefix) it didnt help. While lutris is “preparing” the lutris process eats 100% of one core with no IO, wine is not yet started at this point (no wine processes). The last time it taken 6 minutes to start. The one before the last ~3 minutes. Its kinda doubles every run… The is nothing useful in debug output.
