Thanks for reporting again. It really helps.
1. You mean in the crafting window? If so, then the game was indeed crashing and I fixed it.
2. Oversight on my part. Was thinking about putting a barrier in front of the entrace for the first two weeks, but I just fixed it in normal way so experienced players can rush the dungeon if they want.
3. Are you talking about the training or working specificaly? Because these two work differently from each other.
Working has a set percentage for the entire week, so 100% chance should mean 7 days of success (Unless I broke something).
Training recalculates the percentage every day, so training with skill at 0 means 100% success chance, like the window says. If you finish one day, your skill increases by one and the chance to train drops to about 98%. So the first training session actualy has a chance of about 88% to not make any mistake for day 7.
If that is the case, then everything works as intended. I will however improve this by showing the percentage for training in the actual working window, so player will know what's going on and why they fail.
I will fix the rest, fix some text related problems. write a short blogpost and release the new version.
Again, thanks for reporting those bugs. It is quite a big game and I can't find them all my self.
