there's a bug with the lizard tf, if you have all lizard tf body parts and use the lizard scales, it freezes the game, if you're missing 0, 1 or 2 parts and use the lizard tf potion, you get the same results
Not sure if that was fixed at one of the available versions. Was using the 0.6.8 one, where the game Soft locked after triggering a TF event. I got the Scales one to that time and picked yes, but nothing happened and I couldn't do anything after it. I already had like some Lizard parts to that time, Tail, Feet, Arms and Ears.
