When you try to put a bucket of spring water from the Biomes o' Plenty in a Buildcraft Tank, it will cause anyone who loads the chunk containing the tank with spring water to instantly crash.

This is especially annoying in a server setting, where people can "grief" each other by placing spring water in their tank. I am then forced to use HawkEye to remove any tank blocks to stop people from crashing.

No crashlog to go on. 95% Chance it's Not BC related, so closing.
