another topic that might be relevant to this:

I've been having trouble with the 'Abilities at a Glance' section of the units info screen not showing up, have pinned it down to an extent as being to do with the selection of the stat_ground bonuses, problem seems to be mainly to do with having -1 and -1 for forest and snow (the last two figures) eg:
stat_ground 1, 2, -1, -1
though some other permutations seems to be doing it to me as well. The full EDU entry for the unit that definitely isn't working is:
Spoiler Alert, click show to read:

stat_food 60, 300
stat_cost 1, 330, 90, 50, 70, 330
ownership vandals

has anyone else experienced that or got any ideas as to why that would be happening?

P.S. attributes like "can form shield wall" are showing up fine in custom battle selection they just don't appear on the unit info screen for that unit....
