Survival: Explosions, Fire spread, water damage not working

There appears to be an issue in survival involving TnT, creepers, fire and other various blocks and entities, for some reason Tnt and creepers don’t cause damage when they explode, and fire does not spread (despite doFireTick being true) water also cannot break torches for some reason. This is the extent of the issue I have noticed so far, and I have a feeling this might have something to do with worldguard, although I’m not sure about the direct cause of the issue.
