Attack disabled without a reason

[facukpo]

This is my first post on this forum so please correct me if I did anything wrong.
I've been working on this map for a very long time now and recently while I was testing it I noticed some of the units have lost the ability to attack. The attack doesn't show at all:

<- Like this

I checked and double checked, attack 1 is enabled and it I haven't touch the values since I made the unit, I don't know why it just stopped working so sudden. This is the attack values I'm using for some extra info:

Any help would be appreciated

Your unit's attack dice/sides per die cannot be 0.

I didn't noticed it was changed, I tought I did that long ago and was working, thank you very much.

To get exactly 350 damage one can simply set damage to 349 and give the unit attack 1 dice with 1 side. This will result in 350-350 damage, removing any randomness while still having nice round numbers.
