I did upload a save with my mods. This bug is reproducible on my Windows 7, 64 bit machine with version 0.11.8.
- Load the save...
- Take the empty blueprint in the tool belt into the "hand" and move it from the lower right corner (of the solar panel / accumulator field to the left) to the higher left corner while creating a blueprint.
- While drawing this rectangle, press Q (or equivalent) to put away the blueprint.
- Go over the blueprint and click on it.
- The game now freezes on my PC.
