It is the apocalypse after all.

Okay, I think I know why the money dump didn't work. That event code is designed for things like buying Rust Rid. If the player doesn't have enough funds, it sets a bit that the event script can check for and branch with, and the funds are not deducted.

The pause could be related to the money removal failure or it could just be the game trying to remove all of those items. It is a very LONG event loop. Try shortening the loop by changing the first value to B0 10 and see if the pause is shortened. It won't remove all the items anymore, but if the pause is shortened that indicates that this event takes too long to execute and a different approach should be used.
