[0.10.1][kovarex] Inaccurate blueprints from the ghost rails

[erikem]

Blueprints created from the ghost with rails sometimes are saved inaccurately
1. Open save file https://dl.dropboxusercontent.com/u/164 ... efects.zip (76mb)
2. Zoom out a bit to see the full ghost (created from blueprint) above the player
3. Capture this ghost (full) with an empty blueprint and save it
4. Compare resulting blueprint with originating ghost

Expected: Blueprint is equal to ghost
Actual: Rail path has been misplaced and blueprint does not correspond to the original ghost


Extra info:

• Sometimes in order to get such "actual" you have to clear the created blueprint after step 3 and repeat step 3 again
• I'm pretty sure that simpler layouts would cause issues too but I didn't really try them
• Not sure if it's only ghost-related or the real items would cause this issue as well

Hello, thank you for the report, it is fixed for 0.10.2 now.

The problem is with positioning blueprint containing rails/train stations created from ghost entities.

The problem is, that rails are aligned to 2x2 grid unline normal entities, and once blueprint contains at least one entity like that, it needs to align to 2x2 as a whole.
The problem is, that the algorithm that looks for the 2x2 aligned entity didn't check it for ghosts correctly.
