Wars | UClans Addon 4.9.0

i have this errors with the addons 

addons must be installed in the /UltimateClans/addons/ folder

Hello good day, to report a bug, some players stay in the arena and it does not teleport them to spawn1 or spawn 2, and I tried to fix it by putting the lobby point in the arena and when the clan war ends it does not take them out of the arena and takes away the kits from the player who is bugged.

hello, kits option exists in config to not clear inventory when war ends.

About the teleport check if any plugin is holding the teleport of players, maybe in combat...

Yes, the option to delete kits I have it enabled, but when a 1x1 war ends for example, one of the players who is participating in the war if the teleport to the exit point and the other player bug does not, or removes the inventory, even happened to me and having server administrator, and was solved by restarting the server, but still happens sometimes, to random players, these are the plugins I have, do you think it is one of them that is generating the problem?

the version of the add-on is the latest and the version of the server on which they occur is 1.17.1 and 1.18.1
