Sry i can not follow your number crushing.
Somehow when i came back to the game the last level completed automatically:
what the?
can only be a bug cause mathematically it's very impossible :-)
and jsut oing by the screenshot here, I am kind of doubting that there are rally 44 level10s on the field as it should be.
more like 7 to be precise.
byut who knows given that you somehow fulfilled the 44 l10 codnition, the game might have judged that you are now in the level 11->level 12 phase so level 10 were now deemdd normal units (and not indestructible as he currently highest tier in your misison ususally is), so the cats merged some and, cause level 11 doesnt exist yet, thevanished into oblivion.
well, doesnt matter, was deifnitely a bug.
