No need for the Image= tag in your art entry. For YR the expands and ecaches need to have md on their end. Example: expandmd02.
Btw, If your using the RockPatch then dont use the number 02 as RP uses that. Personally I always go for numbers after 10.
Not using RP and ive tried without the image tag at start stil nothing but il try once more for fun lol. Btw do i need both expandmd and ecachemd or can i just use expand as its only the 1 tank unit
EDIT nope deleting the image tag and renaming the to expandmd10 didnt work stil invisible :(
