It's a very elusive crash unfortunately, and since it has nothing from the mod code in the error I need to dig around and/or experiment to see what causes it, but to do that I need to cause the crash in the first place, which it hasn't happened in my DS so far.

If it happens reliably for you, please provide a world with the grids just before bringing the weldpads together (and a way for me to find said grids).

it happens reliably, yes.
does your mod create logs? is there a way to enable debug for it?

well. forget about it. seems that the mod loading order makes difference. I changed to top, e now it works.

There's nothing I can have in the logs for something like this, what I need to test is with a debugger attached to the game to see the game state and experiment with things in my own code, the world is critical for that.

That sounds very unlikely, it's more likely that the crash itself is random. But also, there's others that have the issue and I can't just tell them to randomly reorder their mods until it works xD
So I still need the world that was having the crashes with the grids causing it ready to be weldpadded.
Or, for the future, right before bringing 2 weldpads together you can do /save to force DS to save and then if it crashes you have the world ready to reproduce the crash.
