Due to the 1.13 update and the update on triggers, unfortunately there's been an issue where there has been multiple declarations in the files:
BarbedWireTrigger.c
DamageTrigger.c
TrapTrigger.c
ScriptedEntities.c
trigger.c

I have commented out what I believe was the right sections to get Buldozer in working order again, however a permanent and more secure fix would be great.
