A check of the mission has the drone blowing up allright after placing a satchel, but nevertheless I have added an explicit allowdamage true statement and cleaned up a mistakenly copied trigger as well. Another test confirmed the proper destruction after placing a satchel. The altered version is included in the update below.
Version 1.4 has three new coops and includes various alterations to existing missions to fix minor problems.
features the defence of Vybor by a recce section against attacks from multiple directions
has a combat engineer squad destroy AT defences and obstacles to allow the advance of friendly forces
is a night raid by a British patrol to locate and destroy caches of MANPADS at Stary Sobor
