yer right there, m8
it's one of those buggy weapons.... well, try something about removing/adding the "PUT" weapon that is needed for a unit to be able to put satchels.
If ya don't have to put anything before you have the bomb, try & remove his "PUT" via the INIT field.
this removeWeapon "PUT"
maybe you can figure out how to let a trigger fire when you get close enough to the pipe to be able to actually grab it... som'n like:
[condition]: player distance crate <4
[activation]: player addWeapon "PUT"
Then you can take the bomb.... and another trigger fires with the condition:
[condition]: player hasWeapon "put"
[activation]: whatever it was... end#1 or alike
fiddle around w/ it mate!
later
