If you right click on a Reactor Controller on a functioning reactor with any Forestry Backpack in resupply (Yellow down arrow mode) in your hand the game will crash and immediately exit.

Very easily repeatable with a minimum size reactor (no fuel required) in a creative world using an empty backpack and

Save file corrupts on second crash, to recover:
Backup your corrupt world (to be safe)
Create a world with the same name as your corrupted one (also the same world type e.g. Biomes O' Plenty and hopefully same seed if you can remember it).
You should load back into your game with everything intact.

For insurance I always do "Re-Create" after making a new world, if I corrupts I just Re-Create the backup with the same name as the old world, preserving all the world settings.

Do you have a stacktrace from this error? This is most likely a Forestry
error and should probably be reported to the Forestry team.

I'm afraid I wouldn't know how to get one, though it's easily repeatable. I'm using BigReactors 0.3.3A and Forestry 2.3.1.1. I've just gone and tested it on every machine I have (I'm using the Direwolf20 modpack with extra mods thrown in) and haven't been able to cause a crash, just the reactor.

All right, I'll see what I can dig up.

I'm sorry I can't be more help. I remember back in 1.4.6 the backpack used to cause a crash when right clicking on crafting table MK3s. The crash only happens when in Resupply (Yellow Arrow) mode. Which is the mode that when you shift+right click on a chest, it dumps its contents into the chest. Which would indicate it's not playing nice with your mods inventory, but this bug happens on just right-click, which wouldn't deposit anything anyway. The crash also happens on the Reactor Control Rod, so I'd guess it's something to do with the custom GUIs though

Also the E-mail notifications stating "Mr. E. Beef" are classic!

I found the Crash Report if that helps:

Hmm. That crash report comes straight from Vanilla Minecraft; looks like
Forestry is trying to send a specific type of packet (type 15, place block)
and Minecraft is crashing while processing that.

Weird.

Okay, after some testing, this is a bug in Forestry. Forestry's backpack does not properly handle any block which has a slotless GUI container. For example, this crash is also reproducible with Thermal Expansion's tesseracts.

I'll report this bug to Forestry.
