Redstone torches break when powered as long as they are mounted to the side of a block. (On top of block, they don't break.) Pistons sometimes bug out and extend even when there is a block between a redstone power block and the piston. That's not supposed to happen. Also, redstone ticks are too slow, torch towers take far longer to update than they should.
SUMMARY: REDSTONE IS MALFUNCTIONING.
Please put only one bug report in each ticket. It is very difficult to keep track of bugs when they are not in their own tickets, and it is easier for you to make multiple tickets than for the mods to separate them.
And please use the search function in the future as all of the issues are reported multiple times.
