U can turn of the settings u think cause the crashes.
Open the ECP_Settings.sqs file in your ECP rout directory.
You will find a fairly well organised script, where u can change certain settings.
Now u mention you think your trouble are caused by the exlposions, u can turn them off.
Find the line :
? [ECP_explosion_enable] call ECP_is_null: ECP_explosion_enable = true
Change true to false. (don't forget to save)
Now restart ofp, you will notice the explosions are turned off.
Don't forget to post your bug, at the thread plank posted!
