Need more information on this I am afraid, what was being done to get the error, and such

[TaoismDeepLake]

The player who reported this was incapable to provide a clear 100% reproduce method.
He said he put HammerLib(hammercore) and this together. When it occured, there was great mist showing on the screen.

How about adding a try-catch and do some log in the catch?

Also, thank you for your timely respond.

[GaeaKat]

Given I can not reproduce it, It isn't something I can randomly try catch. the exception there tells me the line and honestly none of that line should EVER be null unless something is playing about removing tile entities.

[TaoismDeepLake]

In that case, I will inform you when further information are provided by that player. Thank you for your support.

[TaoismDeepLake]

Further info are provided by that player.
I have identified two type of TileEntityFunnelRenderer crashes from the info. Say that they are Type A and Type B.
Type A is that TileEntityFunnelRenderer.java:45 crash. The "Eldritch Guardian" entity in Thaumcraft6 brings strong mist when it shows up. If "fast render" of optifine is turned ON, it will crash as the mist arise.
Type B comes with TileEntityFunnel.java:111 log, which has HammerLib in its stacktrace, attached as follow:

It appeares randomly if "fast render" of optifine is turned OFF.

P.S. "Fast render" is "快速渲染" in Chinese, and I'm not 100% sure about its English origin, it could be "Quick Render" "Swift Render"or such, as I do not use Optifine myself.
It is possible that Optifine caused this, as optifine is reported to cause strange bugs in Cyber-brick's Spiders2.0 mod.
