To the Super Stick:
So the only posible way is to ask the makes of the other mods not to destroy a forcefield ?
Could you cange the block, so that it dropps nothing if destroyaed like glass ?
To the instand replace: one option would be putting the time in the .cfg file. People whon want to check it 20 times a sec should do it but CPU may becomme stressed
Isn't there a function with will be called by minecraft if a nearby block is destroyed ?
e.g. if you destroy a block and above is a door the door will be destroyed right instantly and i don't think there is a timer which check's this every ms...
i have i idea to fix it all hm need 1 week+
