Restart the server helps.

@Njet75 What version are you on? And what Forge version?

Tested with Forge 2655 and 2618 and nuclearphysics-1.12.2-0.1.31.jar and nuclearphysics-1.12.2-0.1.30.jar .
Diffrent constellations with these versions.
Same result.Takes diffrent amount of time until the log shows.

From timt to time.

@Njet75 That last crash, do you do anything specific when that happens?

Only moving around nearby.

@Njet75 I've tried to look into the first issue, and i might possibly have found a fix. But i'm having a hard time reproducing the issue, so could you please help me out by trying this dev build?
https://halvors.org/download/nuclearphysics-1.12.2-0.1.33-dev.jar

Of Course :).
Testing and will get back with result.

/Michael

@Njet75 Hmm, so you use GasFunnel's in your setup, not ElectricTurbines?

Could you try out the lastest build, it contains some fixes that possibly solves the issue.

@Njet75 Think i figured what's wrong here. Will do some testing and get back to you with more details!

@Njet75 There still seems to be som funky buisness going on, but atleast now it doesn't hard crash like before. I'll continue looking into this, but in the meantime you could try out this: https://halvors.org/download/nuclearphysics-1.12.2-0.1.34-dev.jar

Let me know about your experience with it 😃

fusion II.txt
Witch Forge did you build aiganst?
Got more text in log with the dev version.
It might be a issue with other mod or Forge fluidhandler
Gonna test some more

@Njet75 I also get the warnings in the log, this is because Nuclear Physics is still experiencing a small bug, but that is a bug that does not break gameplay, what's actually happening is that sometimes it fails adding temperature to a block, and instead it does so the next tick.
Solution so far is a but noisy, you may see some errors in the log, but it will not crash game.

The actual game crash you're experiencing is by other developers suggested to be because of Optifine. Could you check with you're enviroment if the game crash still happens with Optifine removed?

EDIT: I think the issue here is that you'r having Optifine installed on your server... Or am i wrong here?

I agree .
I think nuclearphysics-1.12.2-0.1.34-dev.jar did the trick.
The reactor works perfect and something else is crashing my game.

Are you running a server or just client? So optifine is not installed on the server?

With the new dev build the reactor dont stop working.
Instead it crashes but nothing points to Nuclear Physics.
Maybe you can make sense of it?
I´ll post the log next time it crasches.
Heres the crash log

Hope this helps. :)

I´m running on client for now.
My modpack is still buggy.
Downgraded to Forge 2618 and extrautils2-1.12-1.7.2.
Been running for Three hours with no crash.
Reactors work perfect.
Have two setups. One with gasfunnels and one without.

@Njet75 Excellent, any reason you're not running the latest RB of Forge? It's now 2655 for 1.12.2.

I was running 2655 but I knew 2618 was stable.
Will try 2655 again and if it doesn´t crash I will be running it again.

@Njet75 Oh i see.

@Njet75 This is finally solved in latest release.
