Need help...Seriously :(

[Soala]

Ok let's say... I think I should post it here

Alright.
I have a playerworld (like most of people )
It's called Silence

I first made a tileset from pics1.png, etc...
First, I don't know how it set it, but I just uploaded the image in RC (images folders)
Then, On the first level (OSL to be more precise), I put the new tileset
I then made a gmap, then the tileset was all over the gmap (which is good cuz I didn't know how I was going to set it over all the levels )

Then I made a new tileset, I wanted it to be more organized.
So everything I changed in the old tileset went on the new one.
But this new one is TYPE1 instead of TYPE0

I uploaded the image to RC, and deleted the image of the old tileset
I tried to have the new one on my server, but it wouldn't show
and I don't know how but the old tileset is still showing, even if I change the level or upload a new one

And anyway

Does someone know if making a new gmap (yeh I plan to change it), if I success by the help of someone to get TYPE1 as tileset, will affect it ?
I mean, you know, will it recognize the cliffs, etc..
Or will I have to do everything myself ?
