I dont do creativity things. I play survival the most. One time in creative, when i was deciding to build a big mansion with a park, a pool and an own rollercoaster, i got distracted and started spawning villagers and mobs inside my unfinished mansion. Creepers exploded and brought down the coaster and insides of the mansion. Then i got angry and started placing tnts all over the park, the place where the pool will be, the coaster and all over the mansion. I ingnited one tnt and in 15 seconds, all i have built in 2 hours have gone.
