This thread is for posting bugs, issues in the game, or any other minor improvements you would like to report. Do not post suggestions for new elements or features here, those should go in the Feedback subforum.

You might also consider reporting bugs on github, so that they don't get lost.

This has always been the case. Coal normally spawns with 110 life and 50 tmp. Without these properties, it will immediately combust.

TPT Multiplayer will take a stamp of the area you loaded in, and send it to other players. This uses TPT's built-in stamp mechanism, which should preserve stack order, although it will change particle IDs / order. Are you loading the stacks from a stamp / save, or using a script to load them?

I mostly made changes to LIGH's .tmp2 property, but I also changed LIGH slightly to kill it if the .life is <= 1, rather than delaying the kill by a frame. That must be what broke it. I could fix it for a future version of TPT.<br/>

The LITH page on the wiki has more info. Be sure to expose the LITH to a lot of CO2 before triggering the "explosion".

They are new in 96.2. Feel free to document them, because the wiki is maintained by the community.

For 96.0 I documented everything in advance of release, but not for 96.2 (I was busy). I've been meaning to document the new stuff in 96.2 soon.
