Problem with the limits of guild members

For weeks there problems with the limit membership in a guild, not only few cases occur but is something that is in all the unions, and the problem lies in the expulsion of members when that happens then a small example I can decipher the problem. When there is a limit of 50 members and 20 members of the guild are expelled, 20 posts have been removed and left in vain as it works out a notice of "the union reached maximum membership" this is annoying and it should be fixed as soon possible please !.
