Probably just me being incompetent somehow, but when I try to select walls or other certain objects using the object selection menu, they are not available in the scenery selection menu in the game. For example, I'm trying to select WALLMN32.DAT which is the wooden wall with the 3 posts that looks very similar to the log entrance style. It's a vanilla RCT2 object. About 50% of the scenarios if I click the checkbox for it, it's not available from the scenery object menu in the game. I've tried backdating all the way to the 1.2.0 stable release and the problem persists.
Here's the kicker, this just started a few hours ago, it was totally fine before and I didn't update when the problem started. I updated to see if that would fix it, but the update completely eliminated all text from the object selection menu, so I tried backdating about 20 versions, still had the issue, so I went all the way back to 1.2.0, and while I have the text back, the original issue of selected objects not being available to be placed persists.
What can I do to solve this issue? A complete wipe and reinstall of RCT2 and OpenRCT2? I really don't want to lose all my saves and CSOs...
