Trying to fill an unheated culture jar with mead must or lager wort throws a NullPointerException from growthcraft.core.shared.tileentity.device.DeviceProgressive.update just after filling (presumably on the first post-fill processing tick). Sake mash and fermented mead don't appear cause the same issue. Heating a culture jar over lava allows for safe insertion of mead must, but after removing the lava, once the jar fully cools (cooking/heat indicator in GUI drops all the way to empty) the same NullPointerException is thrown.

Haven't tested other liquids yet.

Example crash report: https://paste.dimdev.org/lazusobosi.mccrash
Versions:

• Growthcraft: Mod info says 4.1.2, Jar archive is labeled 1.12.2-4.1.2.200.DEV.a5433513
• Forge: 1.12.2-14.23.5.2847-universal

This appears to be new behavior for the above version, as the previous '4.1.2' (which just has 4.1.2 in the jar name) from the same modpack did not crash under the same conditions.

I'm happy to try and provide more information, but I admittedly have no idea how to Growthcraft (another player on our server found the issue) so I'm not sure what to test or preemptively provide.
