We are aware of them, but they have low priority. We have more important things to do. They go here in order not to take space in the main bug thread list.
Reproduction:
- place an assembler 2
- ctrl-click it with a stack of speed 1, floating text says: "-2 Speed module (48)"
- ctrl-click it with a stack of speed 2, floating text says: "-2 Speed module 2 (48)"
Two speed 1 modules were moved back to player inventory during the upgrade, so OP expects this to be reflected in an additional message.
