Just noticed it.
For example - batbox won't explode if we power it with 100 solar panels, or 3 other batboxes.
This also applies to cables, at least to tin/copper ones.
Another thing: what's the tin cable loss per block? I gave up with testing after I received 1eu/t over 64 blocks from a solar panel.
Another thing: doubleclicking on a rubber tree with a treetap will sometimes give you double rubber (any amount from 1+1 to 3+3).
Another thing: once removed manually, mining pipe tail (block id 244) can't be used anymore.
