When I change room text saying "The Quick Brown Fox.." shows up
This is a bug I should fix, but you can work around it by putting the code Consume at the end of the script (instead of End)
The reason it happens is because changing the room doesn't "block" the script, so the engine thinks the interaction didn't do anything. Then it brings up the "you cant use that" line which gets busted when the room changes. Consume will tell the engine that the script DID do something.
