[Genhis][2.0.15] Upgrade planner won't downgrade modules after downgrade of assembler

[Gandamir]

Steps to reproduce:
- Place a Assembler 3 with 4 T3 modules in it
- Downgrade Assembler 3 to Assembler 2 using an Upgrade Planner
- Attempt to downgrade T3 modules to T2 using an Upgrade Planner

Only 2 of the modules will be downgraded, the others are able to be downgraded manually by opening the assembler.

Thanks for the report, this is fixed for 2.0.48.
