the materials seem to be broken

Unlock the tech tree mat and then select all the cards and tech tree mat. Right click and save as object. Load up preferred mod and click Objects -> Saved objects to bring in the mat with the cards. Feel free to delete the tech cards in the original mod (not the race specific techs).

Or just select everything as before and ctrl+C to copy, load up preferred mod, ctrl+V to past

Or load up preferred mod. Expand this mod and manually load in the tech tree and each individual card. Probably the worst way to do it.

I absolutely love the teck tree layout on this one, is it possible to integrate that object and feature into the main game file? I don't know how this works.

By token sweepers you mean the graveyard bags? The map tool should be easily deleted once setup is finished. And thanks, the tech tree was quite the bitch to get right and compact.

This is looking great! Would it be possible to get the token sweepers on the drawers and the map tools (maybe on some floating or disposable platform since they are only relevant before the game starts)
