Support Request: Possible issue with removing machines from world and a question on reactors.

Good morning guys. I have come across a possible bug in 8.10. I was removing machines with my wrench and on the 4th machine the game freezes up and kicks me to a black screen. Now I don't know if this is IC or if it is one of the following mods:
BuildCraft v1.7.3.1
Integrated Redstone v1.7.3

If someone could be so kind to walk me through how to get the game to record errors I could do that for you guys. I haven't attempted this on SSP only on SMP.

My reactor question:
I am working on making (hopefully) a fully automated factory on my SMP server. To do this I am going to use Reactors to power everything (as I have sadly discovered that I cannot run HV from the surface down to the basement). These reactors are going to be underground and of course heavily protected from any accidents :). My idea for this was to use Buildcraft tubes to run uranium into a core reactor to process the ignots and then have it dispersed to my various power reactors. My question comes in at the power reactors. I noticed the buildcraft tubes can only be hooked in the top or bottom of a machine to get material in. To get the ignots in to the reactor I would have to run a tube underneath the reactor and have the power cable come out the top of the reactor. Is this possible?

Okay that was what I was looking for. HV only emits 2000EU current from the top which makes it impossible to run the wire downward. The only work around I have seen is to have the power generators underground (IE reactor) and use HV Transformers to route the power upwards.

Aiden that is interesting, in all my testing I could not get the HV line to bend. I always went with a design like this:

That is okay I was testing on a SSP world and I found that the reactor has a chance of going meltdown while just processing uranium into ignots. I think I am going to route solar panels in to the base or something else.

This just happened a minute ago. All the reactor was tasked to do is process uranium. Then the ignots would of been placed into a storage container via tubes and sent on to the powering reactor.
