I'm unable to perform actions with two of my armies. When I click to select them, the selection window remains on the last army selected (screenshot attached). In the screenshot, the army of 6 and the army of 1 is affected. I can click to select, but the army info does not display, and no actions can be performed. I think it was caused by ransacking the city using the army of 6, but I can't be sure, and it also affects an army unrelated to the 6. This happened previously and I reloaded an earlier save, so I think it may be something that happens in the background over these few turns. I am unable to continue the game because of this, as the armies are in idle status

Expected behaviour is that these armies should remain functional

Update on this... I think it has something to do with upgrading my Mortars to Siege Artillery. Just tried upgrading one unit in a reload of the saves provided above, and that unit encountered the issue I described
