I cannot research "Warptorio synthetic promethium". It seems to be locked behind "Warp garden platform addon" which seems to be a infinite research.

I am running:
- base 2.1.12
- elevated-rails 2.1.12
- recycler 2.1.12
- quality 2.1.12
- space-age 2.1.12
- warptorio-space-age 0.4.1

Here is a screenshot of the research screen:

I hope i explained it well enough. Let me know if I can provide any further information. Thank you very much for this great mod. I had a great time playing it so far.

This will be fixed in 0.4.2 just getting last few fixes in there

Great. Thank you very much.
