Hello, just got the game and I'm loving it but I found one mistake. It seems like Vorpal Guns share some code with Overwatches and there fore don't work when you put Stabilizer Mods on them. Rules as written, you should be able to do that thought as Ordnance doesn't prevent you to use weapons as reactions.

I believe that the reason you can’t owerwatch with vorpals is because they have the rules text:

Gain the SNICKER-SNACK reaction, which is the only way you can attack with this weapon.

So if they’re able to overwatch normally, when you don’t have Stabilizer Mods on them, that’s actually a bug. Is that what you’re seeing?

No sorry, your misunderstanding me, it's snicker snack that won't trigger because I have Stabilizer mods installed. The part about overwatch is me speculating why that could be. 

Ah! I see — great, noted.

Following up, I found the issue: there’s a “can fire ordnance” flag that gets set and unset at the start of a unit’s turn that prevents firing ordnance-tagged weapons outside of it. I’ve modified things so more generally ordnance actions triggered as rxns skips this check, which also fixes a kludge I implemented that let Sniper’s Moving Target fire its ordnance rifle off-turn.
