Getting a game breaking bug if I ask Steph to test a new serum, it starts giving errors that the serum update function has too few parameters every turn and the serum never time out, however more critically no work is being done, you can skip the error but all end of turn updates break so research is not happening and production is not getting done meaning the game can’t really progress.

Uodate 39.2. Game still broken. Girls do not generate supply/research/production/HR/marketing once you cum in one. Game still has ignorable crash after but game bugged and considering basic design and aim, totally and 100% unplayable.

Come on Vren. BUG TEST. If your ‘bug testers’ are so bad they miss these fatal bugs, or suck your arse so much they don’t tell you, get new ones, JUST STOP RELEASING BROKEN UPDATES.

What you are saying, when you can’t choose a girl and the whole game can’t be played it seems kinda pointless to download it. The concept is great but it needs quite a few bug fixes with the next updates instead of new game elements fix the existing ones. It feels like a Cyberpunk 2077 game sad

Playing for 4 hours, and the sex scene is very disappointed, and the text is too small
