My son's Mincraft edition is throwing the following error when he goes into his significantly well built out world:

The game crashed whilst tesselating block in world
Error: java.lang.NullPointerException: Tesselating block in world

I looked at the other errors (like #606) and it seems that @cam72cam might need to see the error log to figure out the issue. The log is attached. I'm hoping you might be able to help.

This should be fixed in modcore

See this
#606

Yes, try that jar in the patched version. I need to release an official update soon with that fix in it

Thanks, I thought about that but had assumed the version I had was already patched.

Question: Should I drop the #606 patched jar into that folder, or remove ImmersiveRailroading-1.5.0_1.12-402 and replace it?

Removing it and replacing it did not work.

replace the jar

did you use the second jar?

I did.

I used:

ImmersiveRailroading-1.6.1_snowfix2

What I'm asking is:

Should I remove ImmersiveRailroading-1.5.0_1.12-402 and replace it with ImmersiveRailroading-1.6.1_snowfix2 or should I keep ImmersiveRailroading-1.5.0_1.12-402 in the dir and just add ImmersiveRailroading-1.6.1_snowfix2 ?

Thanks @cam72cam

OK, thanks. Replaced it.

Same Tesselating block error.

Hmm, that's a different crash. Let me look into it and try to put together a patch for you soon.

Macos upgrade does not have an impact. It's just a bug in my code that I need to patch

@aagha Were you playing it on mac? After upgrading the os to macos 10.14.6 I encountered the similar error I had never seen before. Here's my log:
