I revisited this & hopefully the spare 555 tile (*ahem* error) is gone. One of the 2 555s didn't have the label/name defined, no idea why it was still there, please let me know if it reappears. For now, I think it's fixed... It only took a few years...?!!!

There is NOT a duplicate 115 tile - BUUUUUT the texture on the 155 is wrong. So it looks like a 115. So I guess there is a duplicate 115, and a missing 155. I'm digging into that, but it's already confusing since I'm looking at a lot of added/updated features in the game, and to be honest I've forgotten most of the basics. Still, there is almost some progress.

Enjoy!
