I know you are not trying to form an ASW TF. I can read.
I am suggesting that in the change from classical WITP to AE, which affected the type of missions an AM was capable of, something has gone awry and that currently in AE perhaps the code does not recognise an AM class which lacks any ASW weapons as being a valid ship to form a minesweeping task force.
Frankly I was trying to give michaelm a leg up in tracking down the source of this prima facie bug and in the process give you a possible explanation, pending michaelm's definitive answer.
As to the internet disclosing the Fugas class was a minesweeper and therefore it is wrongly equipped in the game, that is an irrelevancy. There is no minesweeping device in the game, thus you can't correctly or incorrectly equip minesweepers in the game. It all depends on whether the game code recognises a class as a valid minesweeper.
Rather than rushing off to the internet to check on the Fugas, have you bothered to check whether the same problem also afflicts the French class I nominated as having the same deficiency. Obviously if the French class can be formed into a minesweeper TF then some other factor is responsible.
Not how you previous post read to me since you talked about ASW but it's no biggy as far as I'm concerned No I don't have any French AM.
Having no idea what a Fugas ship was in real life, checking on the internet is a valid option. It could have been a minelayer for all I knew and therefore it's classification as an AM in the game would be wrong and, like you I was attempting to isolate the problem.
