[General] A Question about Orc Burrow-based defense ability

[Leo Akastenix]

Just a nagging feeling to ask. I have a Town Hall esque structure with a working Orc Burrow esque setup. I have never seen this before, but know some mods have done this but is upgrading the structure prohibited while units are garrisoned? If not, would it crash or remove units if the structure gets upgraded if upgrading them isn't prohibited. Its a simple question but I hope this can be quickly answered.

I know you're looking for a quick answer for a simple question, but it sounds like you're just 1 step away from testing this out yourself. Add an upgrade to your Town Hall and let us know what happens, I'm pretty curious about this myself.

Buildings can be upgraded with a unit in cargo.
As far as I know, there are no obvious problems in doing so.
