Okay, there are three things in the game where you best do them when Vruk says too or you're toast (Midge posted about two of them here:
https://f95zone.to/threads/the-rise-of-vruk-v0-15-killjoytrv.76318/post-6712477). Another, which was supposed to have been fixed and yet wasn't (has now and won't be an issue going fwd). That's four and not "many" given all the stuff in game as of 0.15.
Some call all of those bugs and others call it player's error. I don't care which side of that debate people fall on. I just know either way, don't miss the key step and you're fine. Midge asked and now I am too, where are all the other bugs in the PC version? Please be as specific as possible. I literally am curious and will look into all of them. I will say this: that blank dialogue box is not on the game side. Not a snowball's chance in Hell that would've been missed by the testers or anyone else playing 0.15 since it's release.
