it works now, just got a whole bunch of different textures for a surrounding coast on all my islands...

shouldn't be rocket science to fix, i'll just do it by hand.

It sometimes happens that when you first make your map_t, that a bunch of values get messed up anyway, usually due to riverbanks or coastlines having different values than whatever value you used for the whole landmass at first (in the tutorial it is given as RGB 7). This happens because of blurring or something perhaps being off with a threshold value ... or whatever. Never really mind the reason. It happens.

But there is no need to correct by hand ... good grief what a waste of time.

Use a magic wand tool on map_t, (I am thinking Paint Shop Pro here), select one of the odd colors out on the landmass, click to select and then select all similar. Then change all into whatever RGB value you wish to have.

Select all wrong values until you have a homogeneous RGB value for the whole landmass, when all land is for instance RGB 7

THEN you can get to work assigning other RGB values for lowland, midland, mountains or whatever.

And a tip - work in layers. This means in a psd file for instance. Give each RGB value a separate layer and build up your map layer by layer, RGB value by RGB value.

When you wish to view the results in the game provisionally, you then save your layered psd map_T to a tga format in GIMP.

But always keep a master layered psd file for your map_t - and for other maps as well for that matter - the ed_m01/02 maps, the map_F, and map_h as well.

It's a bit more work at first, but it makes it so much easier to bring corrections to a map afterwards. All you need do is make the changes to the appropriate layer. Not to the whole map.
