Every time I try to make an elevator, the game crashes. I have two crash reports. The first is with all my other mods present and the second is just thutcore and the elevator mod present.
All of my mods present.txt
No other mods present.txt

Ok the mod worked great with your fix but now that I've added my other mods back to the folder it crashed like before. I'm assuming it's a conflict with another mod. Here's the crash report. Any insight?
New Elevator Crash Report.txt

I am also seeing a crash when creating an elevator, regardless of other mods. Using 1.15.2, happens with or without other mods present. I am seeing some console logs on startup indicating that the mod isn't receiving the block IDs it's expecting, not sure if that's related.

can you include the crash report from yours?

If this issue still occurs for 1.15.2, please re-make in https://github.com/Thuts-Mods/ThutTech/issues
