Weird bug : engy stuck at the factory

[odin002]

Hello, in the game 2744897, look the first factory, I was making an engy, then I canceled the move order from the factory (right click + shift + ctrl, something like that) just before the engy is made (or when he's made..) and the engy was stuck at the factory and couldn't leave the factory, I tried to select the engy and give him a move order, I couldn't, tried to move the rally point of the fact, did nothing. I tried to ctrl k my factory, and then select the engy and give him a move order : nothing. tried to reclaim the factory, nothing.

What the ... is that? xD
Weird.
