So I just solved the puzzle in the lava room with the statues where you have to shoot the faces with the orbs. When I step onto the teleported the game crashes. It crashes so badly that it locks up everything to the point where the only way to fix it is to restart my computer.

I saved the game right before I was about to step on to the teleporter. After I reloaded to try again, the same thing happened and now the game crashes whenever I take anything out of my inventory and also when that one statue shoots its fire ball. I even left the lave room and tried to take something out of my inventory in another room and the game still crashed. I'm stuck now and I can't advance any further. Unfortunately only have the one save file. Something has caused my game to break.

Anyone have a possible solution to try? I'm patched up to 1.19f. I did download patch 1.19h but as far as I can tell the patch was never applied. The journal says 1.19f still.

Edit: After playing around with it quite a bit and experimenting with the fly cheat it seems like a section of that cell is corrupted or something. The corrupted part is the room with the mimic and the orb and everything past it. Unfortunately the only solution seems to be starting a new game. I'm still open to advice if anyone has any. I'm actually pretty worried that when I get back around to that part of the game I'll have the same problem.

Sorry everyone for bringing up this thread (it isn’t that old) and I don’t know if OP is still interested in it, but, since I am currently playing Ultima 9 for a second time and got stuck at this particular spot, I think it’s in order to say that I have found a solution, if it can help others too.
First of all, to play games with using only one save slot at any time is WRONG, generally speaking. Even more so when we’re talking about large games, where anything can go wrong. I admit I have done it before too, but Venetica game taught me this lesson: When a game makes available for you multiple save slots, USE THEM.
Secondly, to the solution at hand. My game too was crashing when attempting to step on the teleporter. Taking OP’s advice, that this section is crashed from the mimic room onwards, I loaded a save when I was already in that room, but I DIDN’T TOUCH the bowl for the orb to appear (so I didn’t have it appeared) and I also DIDN’T TOUCH the mimic (so I didn’t have it standing and walking towards me). I just pressed the button on the wall near the second door of the room, it opened and I exited the room.
Then I did the proper actions in the lava room and this time the teleporter worked.
Thank God, I can keep moving.

Funny thing is that I played this game for a first time about 2 years ago (early-'21) and I don't remember facing this bug!
