The current version seems to have some game-breaking bugs unfortunately. I restarted the program after the .exe stopped working in the middle of combat, and when I came back, I couldn't load my save. Nothing pops up when I click on it even after waiting a while, then I tried to start a new game, nothing happened either. Only the 'Options' button worked as intended.
When clicking on the buttons multiple times out of frustration, the game caused my exterior devices to disconnect and freezes my processor. Note, the previous version of 15.2 never gave me any of these problems. And my computer isn't a potato device either, I can play Black Myth Wukong at Ultra graphic settings with 45 - 60 FPS, so I highly doubt its a tech issue.
Some in-game bugs as well. Spamming "Talk" to increase a servants relationship causes them to shift through their animation cycle so fast it clips their model into the floor. Also, pressing x3 Speed causes the game to lag. Once again, none of these were an issue in the previous version. The tutorial also seemed to have disappeared.
Hopefully these issues get optimized/fixed soon.
