No probs. I've only done two so far, and they were ones that killed you when you warped to them. I'm going to wait a day or two before I go through the rest.
How do you a) go through the warp points and b) remove them?
Only I might use a few temp ones to finish my red arrows and then want to axe them off afterwards. It's taking me longer and longer to hop between them all now.
You can see all warps by doing /listwarps, so then it's just a case of warping to each one and then, if it seems useless, deleting it using /removewarp warpname (or whatever the command is).
I was trying to get an auto JPG conversion thing going last night, but I was too tired and the server was complaining it didn't have enough memory to convert it. :(
I definitely need to spend some time looking at how the mappers work and figure out if my layered image idea makes any sense at all. :S
