We solved this in different way about 2 months ago. When parties are over limit they are disbanding lowest tier troops. It should already be in 1.4.2, isnt it there? Does at 1.4.2 player clan parties still suffer from losing high tier troops due to having more man than party size limit?
If you have the save file, maybe bring it up with the devs - if the AI is recruiting too many troops, possibly through prisoners, have them donate them all away to garrison.
