Lichess Analysis Bug

Frequently when I analyze my games there have been blunders saying "Blunder. CHeckmate is now unavoidable," even when the move before, I still had forced checkmate
It would be helpful if you posted examples
That's not a bug. Every winning position is a forced mate. If it wasn't, it wouldn't be winning.

Most analyses end before the forced mate is found. That's unavoidable.

Plenty of forced mates can be found if you use more computer resources than the fishnet analysis is allowed to use.

I give the same advice to everyone who wants the fishnet analysis to do more. Loan some computer power.

The server analysis doesn't show a forced mate on the move before. Maybe you're confusing the notation? The evaluation after a move applies to the position after that move (which can in some way also be considered the evaluation of that move) and the comment afterwards applies to the same move.

Though if you let Stockfish run locally for a little bit it indeed finds a mate in 18 on the previous move. But the server analysis didn't analyze that deep. That's somewhat unavoidable as Stinger already pointed out. All actually winning positions are forced mate but unless the mate is very short, we can't check it.
