bug

Landed on vulcanite, extracted a resource, thus the technology was studied, for the next technology it is necessary to make a new resource. I made it, but the technology is not being studied, I think this is a bug, I attach a photo

Hello, based on the picture, the technology has another prerquisite (the yellow box above your technology), so you first need to unlock that to make this one unlock.
