In some versus, ranked games, my factorys are not working well and are freezing in the end of production of siege tanks and Thors (only sometimes and in some games); the unit production never ends and it keep stoped, frozen, making me have to cancel that unit production, losing all the time wasted on its production, and needing to give a new production order for a new unit.
Obs: When ordering to build new units after that unit that was frozen and stoped; the next units waiting on the line never begins to start their production, while the first unit keeps frozen and never getting ready, making me need to cancel the frozen unit production. So I can start to make new units again.
This is what happens when units don’t have the space to exit a building.
I think you should at least get an error message in this case.
If those also appear in replays, you may want to play a replay of it happening with all options to have errors in sound and visuals, and if there’s indeed nothing at all, then you may have found a genuine bug.
