PLEASE OPTIMIZE THIS SOON IT STILL CRASHES WHEN JUMPING

There was a beta out to find problems like these, but they didn't come up. No need to insist like, one day after, I saw the issue, I don't have too much time to work on it. But, I'll look into it and post an update as soon as possible. Thank you.

Also, can you please describe the issue a little better? Like, when does it happen? Do you play singleplayer or you have the mod on the server? What light type do you have? What target? Can you provide the log files too? Etc.

I'm not sure this is related to the jumping crash thing, so please provide information on that kind of crash as well.

Also, here is a dev build that should have fixed the bug. Please test it.

I was hosting a server with essential I had wind targetted to myself but it doesn't really have a pattern it only sometimes happens when I jump

So it's the (dedicated) server that crashes? Btw, the test release should probably work then, let me know.

I'll see if it works

I can also send a list of the mods I have installed if needed

It Still Crashes Randomly this time I was just killing a creeper but I landed a crit and it crashed, I put a list of mods under the crash report

This one is related to an entity and continuity, not LightWithin

so if i remove continuity it should hopefully not crash?

Most likely

Oddly my friend also has similiar issue? I don't have full logs, as he only sent this crash report - Not sure about the settings of how it happened, so I'm really sorry I can't provide any more information about this, except that something might be up

Ah. I will need a bit more context like what light type and target they had, if they were on a server and full logs if possibile. But I may have spotted the issue.

Also when did this happen?
EDIT: wait this should have been fixed already, what's going on here? What version of the mod are you using?

EDIT 2: I just checked again and without more context, I'm really not sure what's wrong since it is the same problem as above, but as I've said it's already fixed. You can also contact me on discord at @Emafire003 if you/your friend find it easier.

@tajemniktv are you/your friend able to provide the logs? Beacuse I can't really reproduce it seems.

Oh shoot, so sorry, we ended up removing LightWithin from the modpack in the end... I'm still unsure what exactly happened prior the the server crash sadly, so I am not able to provide more information sadly...

It could be a mod compatibility issue, as it were the early days of the modpack we were cooking. But if noone else seems to be experiencing this anymore, then not sure if it's worth keeping the issue on the tracker open. Really sorry I couldn't be more helpful with this one:x

I've modified the code anyway, using another type of map, and hopefully should be fixed anyway in the next release

Oh - I will be looking out for the stable release then and ask my friend what he thinks about trying it out again. I remember him saying that it's such a cool mod and he was a bit down we had to remove it, but that's what he decided was the best, as the number of issues happening with the modpack back then, was enormous and I think he wasn't in the mood for debugging lmao

@tajemniktv Hey, if you want to help https://github.com/Emafire003/LightWithin/releases/tag/v1.1.3-dev try out that version and let me know if the issue keeps happening. (It shouldn't)
