Feral Heart

So I'm trying to fix the problem some of my members in my map are getting.
Basically the oak tree's fall and snow (orange leaves and then just branches) that are found in FH+ that are basically only have different leaves from FH's oak trees. They cannot see the leaves.

I've tried to give them the files and replace the ones in the tree folder, put it in objects, my_objects, textures, and everything I can think of but they refuse to show up. Anyone have an idea on how to fix this?

So after I exported a map, Fh decides to troll me and crashes right when I click to start it.
Normally this does it when it, for some reason, wants to duplicate particles but I already removed all the ones that have a _0 at them. Is there any other issue out there that causes this?

Also please do not say reinstall. I tried and attempted to move over meshes and such.

So one of my maps had been working good.
It had some flaws of bad tokens when entering it from time to time due to its meshes but
that never really stopped it from working for all.

Then while I was away, one of the people that use the map
and all the others who had been in that map, now say that
it is saying Cannot connect to map server. Now this is my own created map
and not one of fh original maps. Is there a way to fix this with out having to adjust the map
and exporting it again?

There seems to be nothing else duplicated anywhere.
Do you think it could be a mesh pack that just has something wrong with it?

That deals with height maps and terrains. I believe my problem might be linked to a certain object possibly GB or GL citystuff maybe.

At times it does make multiple particle files but it'll cause me to crash while exporting without the double particle problem arising so it isn't that 98% of the time.

That link doesn't explain my problem.
