Had an issue with this BP 'misbehaving' in factory; After a few seconds it would vanish (?) and the factory no longer accepts mats. I could eventually start production, but factory returned to empty again, although it left the timer running until I re-load the save.

In Creative I removed 3 sv-deco blocks (cause I had no idea what they were, lol), saved on new name, and now it behaves as normal...... I expect no further issues. Looking forward to test flight ;) no mats were lost.

google for Zakuul Taxi

I also like the design on the second to last picture. Where can I find that model?
