For me it appears that in the SCUBA showcase mission that artillery support is missing from the radio menu thus its imposable to call an artillery strike as before when playing the mission using v0.67.106210
(no missions, mods or other files in use)
{F19431} {F19432}
Perhaps you also need to make a better "5" font so it won’t look like a "6" when scaled down!

It is still broken, though the mortar now appears in the supports menu with an icon on the left/top of the screen signifying availability, however it is ultimately broken at the point you would select the number of rounds to fire (1 or 2)
If you press “0” > “8” (supports) > ”1” (artillery strike) > “1” (mk8 mortar [8 echo]) >
You get on on screen error/script message
“Error in expression <omm_burst" + format [", ETA %1s", round getArtilleryETA [vehicle _provider, _sup> Error position: <getArtilleryETA [vehicle _provider, _sup> Error format: Undefined variable in expression: getartilleryeta”

edit: FYI: one .rpt was with "r3f_armes.pbo" (mod) loaded, the other .rpt was with it off thus mod free, also the mortar inc the AI man with it is in place on the map, as I also ran to its position.
As of the v0.59.105634 build that came out today 23rd May, the problem seems to be fixed.
You can disregard my early post (0028645) above from today, as that was the prior v0.59.105592 build.
