Hi, since the last Patch it seems it is no longer possible to rotate both the large and the hugh storage tanks. This applys to both copying and blueprints. It seems to be unrelated to other mods: I deactivated all other mods (except Space Age and dependencies) and the bug persisted.

Steps to reproduce:
- Start a new game (optimally in editor)
- Place a storage tank
- Copy/Create a blueprint
- When trying to rotate, the error message ("Blueprint mit großer Lagertank kann nicht gedreht werden") is displayed

After looking into the code I found that both tank entities contain:

flags = { "placeable-player", "player-creation", "not-rotatable" },

For testing purposes I removed the "not-rotatable" flag, after which it worked again as it did before the patch. I do, however, not know, if this might cause something else to fail, I only did a short test, where it worked fine.

I will continue to play with my fix and report, if I notice that anything breaks

I'd like to know the answer to this too. Removing the flag from both entities seems to solve the matter and I can rotate my blueprints that contain these entities again. The fix is simple and I raised an issue on his github, but it's unclear if the mod author is on hiatus.
