I'm going to start a new game in a new world. I just dumped 400 upgrade stones into one hero (because I was tired of dying all the time) and then visited an Ice Age Plains. The very first house I enter, I find I am right next to a secret stash. So I walk into that doorway only to be greeted by two robots who bounce me between them until I die. I couldn't move, the room was too low for me to double-jump away, and there were no spells I had which could knock them back. I even tried to throw crates, but that only prolonged my death since it glitched me into a crate and I just hovered in air until the crate was destroyed and the bouncing process started all over again. I'm not going to go back to 100 health trying to scavenge for upgrade stones in Tier 2.
As for the button click, it's to the point I completely turned off the sound again and this time It's staying off. I cannot stand it any longer, so until I can locate that sound file and replace it with something else, I am forced to play with no sound.
Lastly, I found another bug, although I'm not sure if it's been reported (I don't get the whole Mantis report thing). Anyways, if you are running from Urban Crawlers and enter a house to flee, then exit the house, you will be glitched inside the crawler - unable to move or jump free. The only way to free yourself is to kill the crawler which results in you getting stuck in the middle of the fireball. Which, if you have my luck, you will just have used your remaining few stones to upgrade a brand new character after losing your main buffed hero, only to find yourself stuck in the middle of a crawler getting shot from two espers and being left with 12 hp when the crawler finally blows up - resulting in yet another death.
