Glitch: Tank stuck while loading riders

[Panzer Lehr]

CMRT 3.0

Weird glitch...tank becomes stuck, it is not bogged or anything, it is perfectly fine, just won't follow orders to move ... in this case it seemed to have happen while loading tank riders ... 8 of 11 infantry guys are on the tank not sure where the missing 3 went (the unit icon is dim) but tank won't move presumably until they finish loading and the guys on the tank I can't select to get orders to get off! It has been like this for around 6+ turns so far.

This has happened before, very frustrating as it is basically a pill box. Surely someone else must have had a similar thing happen to them.

Update: Tank seem to have cleared itself but one infantry guy magically teleported way behing enemy lines
