[Haunted Evil Pajamas]

I don't know if this was intended or not, but when you capture and convert Gold Beetle's into mercenaries they no longer have the Rail Shot spell. I have 4 level 75 Gold Beetles who shot me with Rail Shot as I was trying to capture them. Considering we still have the absolute units that are Grindylows available as mercs, I don't see how much worse some laser shooting beetles would be.

How to replicate: Just capture a beetle and see it does not come with a portable laser cannon.

I don't recall if other monsters who become mercs lose some abilities aside from a passive or something in the Grindylows case.
(Personally I love the fact the beetles have this spell, it caught me off guard and I got a huge laugh out of it.)
