Upgrading a hatchery to a lair without sufficient resources caused an issue where i was locked out of controlling units(they kept doing their thing, building and gathering resources etc), and the “not enough gas” line looped over and over again. This happened until i got enough resources, whereupon the lair started building. Might be lag related but i didn’t see any units lagging.
Haven’t noticed this before patch 1.23.5 so i think it was caused by that.
