What I mean is when I power an inverter it visually turns dark red (so do the cables it's powering), but any blocks connected to it in a seven block radius around it are powered anyway. I have tested this with both vanilla and modded blocks with the same results, I am running this on a modified version of FTB horizons daybreaker, which includes fastcraft. this problem begun when I updated to the latest version on curse: 0.2.962.
edit: It appears to occur when red allow wires connecting the power source to the inverter has become 17 blocks long

Updated with pictures

Further testing has revealed a few things, first of all that this bug applies to every kind of red alloy wire (although bluestone is strangely free of this bug), second of all a simple lever doesn't seem to be causing the problems, I shall experiment further to find out which part of my system is causing this and update the post with the results

The bug appears to occur when the cable connecting the power is 17 blocks long
