Enigmatica 6 0.4.3 (official server)

When using the Create handheld blockzapper, with glassential luminous glass as the selected block, the client sometimes crashes and then instacrashes upon re-logging. I feel like I have used luminous glass with the blockzapper without a crash at times before, so it may be some specific combo that's causing the crash, but I'm not positive. I've had the issue happen both on a single-player game on a previous version (don't remember if it was 0.4.0 or the last 0.3 version) and just had it happen again while on the official server.

Logs
This is the original crash report and then a second crash report trying to re-log.

Thanks for the report, I relayed it :)
