Potential Locks & Cash Shop

Hello People of Ragezone!

I recently came back to the scripting of MS and ran into a weird thing. It's probably just a missing code somewhere but... When I use Potential locks and chose the line I wanted to keep, it disappeared anyway. Any idea what is missing? (probably in cashitemhandler or something)

Also, I was wondering how you can change what is available in the cash shop. (not just block it)

I am using v111 lithium. Willing to upgrade the server to a newer version if that's what it takes. (would rather not due to the effort it took to get the last one to work :D:)

Also, I found out that the computer hosting has the PIC problem...takes a few tries to get in. Have to set the 'logged in' to 0 every time. I tried all the fixes in the released section to no avail. I'm not asking to be 'spoonfed'. Just want to learn how to fix these things. I am a beginner coder but I am willing to learn. I have done some fixes in the past. I would appreciate any constructive input that anyone can give.

Update and bump

Still have the three problems above but I think the potential lock is nonexistent in the code. I was poking about in the source and found where the item should be (i think) which is InventoryHandler.java based on the fact that's where the cubes are. Does anyone have working potential locks?
