After a TNT is ignited,it will flash several times as intended.Then,when it is supposed to explode it will disappear.At this time,any blocks placed at the original TNT position will disappear.After a while it will explode.If you exit and enter the map again,the invisible TNTs will show up and explode as normal.This bug usually happens in amplified maps but can happen anywhere.
