Yes sorry all the Voobly server is down.
Nothing more we can do at present sorry, the hosting service OVH are having a major problem at present and we are not the only site affected
We are waiting for them to call us back with an update, and have support tickets etc.
Doing all we can and fingers crossed they fix it soon.
We'll have a concrete ETA within the next hour.

Check the mod priority, some don't work with others so try and move the tree mod up in the list if it isn't already.
You can also try sub/unsub from the mod. In the old workshop the best way to fix mod issues was to just delete them all from the mod folder and let them re-download. no need to resub them. Haven't had to do that in the 4.x shop yet. It's usually just a priority thing and making sure they play well together.
Of course there is the pussywood mod by itself but there are also a number of texture packs that include that in them. Just something to keep in mind as you troubleshoot.

Do you have to download a separate client?
