Disclaimer: I don't know if this goes in the beta bugs section on account of version name.

Something under the hood seems to have busted the Tactician skill On My Mark.

Replication of bug: Equip skill, activate

Bug nature: Skill isn't working

Steps of verification: Unequipped all items, tested with high level mercenary, unequipped skill, re-equipped.

If it ain't broke for anyone else I don't know what's going on with me.

I believe this was corrected in 2.26d

It was replaced with an interesting mutation of it. On My Mark now just doesn't function during Back Attacks, then proceeds to work after the surprise round as normal.
