Okay, so i am making (actually made) a custom reticle but can't get it to ingame, because after the first compile, it refuses to compile again, the error it gives " ### ERROR can't extract sprites without a valid plate" anyone know what this means?

Tool is never wrong. When something doesn't work, it's your fault. I'm not exactly sure what you're problem might be, (post entire latest debug.txt mb?) but I would recommend decompiling a reticle bitmap that bungie made and using that tif file as a comparative reference.

Did i say it was tools fault? no. That was the whole debug, minus two more of those (i have 3 reticle in that folder) and without the tool beta map and the ToD :)
