yeaaa same with me i cant destroy some dirt and others with tnt it wasnt even in water it was on land and it still not destroy it i need to destroy it with shovel takes sooo long i need it fixed!!!
lolz his gamemode was creative lolz and its not even a bug or anything its normal in minecraft....
its not an issue to other ppl much but it is for me coz i need it to make a fire
to fix it all u have to do is destroy the block next to where u want to place the torch and it will be all goods and then put the block back i think its just because of the signs or something i dunno i hope it will get fixed in next update
