This is not a gamebreaking issue, and is a bit of a non-issue that’s probably just a result of the fact that the Battlegrounds mode is in beta; however, I just played a game as Dancin’ Deryl, wherein I buffed a Replicating Menace.
When I combined the Menace with a Psych-o-Tron, the buff that I gave the replicating menace didn’t show up in the list of buffs. I confirmed that it wasn’t because it ran out of space by buffing it with a Metaltooth Leaper, which showed up right away.
Metaltooth Leaper is different from the Replicating Menace. When the Psychotron was magnetized, it gained a buff that refers to the Menace, but it doesn’t count the buffs given to the Menace itself in the buffs section, since technically they were given to said Menace while it was still its own entity.
That being said, if there was a way to “demagnetize” mechs to separate them from eachother, you’d likely end up with a buffed Menace, with said buff visible on its info card, on the board since the game still keeps the unique ID of that Menace in storage.
I assume that is how it knows to add even the buffed stats of magnetizable mechs to the recipient & for Kangor’s Endless Army to work correctly.
Someone more knowledgeable feel free to prove me wrong!
