Wow, thanx for the mod tip (I believe your mode is even better than normal TPT v83.0, very cool features!). About the stamps problem, I believe that it's simply because part of the "stamps" DEF file was deleted. I'm transcribing all my stamps' names to that file from scratch. I will post the results.
I found a small but irritating glitch. NITR + FIRW+ignition leaves behind BHOL.
And come to think of it, I'm not sure if this is a glitch or meant to happen. Molten thermite [LAVA (THRM)] turns into BMTL when cooled.
And another (how am I managing to glitch it so much?) The tools can be flattened.This could be quite useful, so perhaps make it an official feature? Anyway, to reproduce, while holding Shift, use enlarge ] a few times. The tool will become wider. Or hold shift and hit [ to get one narrower. To set it back to normal, you can change the size using the method I named or go down to 1 pixel and come back up.
