is no runner laster version mekanism

Yes, it doesn't work for me too: Mekanism-1.16.5-10.1.0.455 and XNetGases-1.16.5-2.3.8. And yes, there is nothing wrong in log.

Just to humor this again, since I tested it in dev last time, I made a fresh 1.16.5 instance with the mod installed. The game launches fine and after making a simple 2 tank setup, gases transfer fine. Can't do anything if there's nothing wrong with the log. I have tested this with latest dependencies and tried both Mekanism-1.16.5-10.1.0.455 and 456

I've tried to create a new game and make two simple tank setup - it works!
But it doesn't work with an existing game.

That's some weird behavior. Did you try to break the tanks/machines and place them again? Might be some weird issue going on with the block entity. If that doesn't work I would do the same with xnet controllers and connectors, but keep in mind that breaking the controller resets(?) the configuration.

I play on my own server, and I tried to break the tanks and place them again. I even changed gamemode to creative and create a new network, but noting changed. Everything is ok except gases don't input and export.

Found the issue, mekanism changed their equals method, so it was checking if the filter has the same amount of gas instead of just the type. This is why our simple tests in a new world probably worked, since we didn't use a filter. Would've probably never noticed this if you didn't send the screenshots. Gonna have a fix up and running asap.

Works fine on my end

I already tried it. "Not running" doesn't help, I need the log

if you tested it, it has the log :)

Works fine on my end

Yes, it does and according to that log there's nothing wrong. If you want me to see what's causing your "not running" issue, I need your log. You can find it in "[Game/Modpack Folder]/logs/latest.log".

if you tested it, it has the log :)

if a dev tests an issue out, and doesnt encounter an issue, there will be no issue logged in the afformentioned log.
Developpers need yours, because it contains the error stack tracing of what went wrong on your end, on your computer, with your game.
Your sassy reply doesnt help anyone. If a dev asks for a log (and mostly certainly after confirming he tried it himself and didnt encounter the same issue), you give it to him, or else he can't do anything, and you'll be stuck with a game that doesnt run as long as you use either this mod, or a mod incompatible with this mod, or whatever the issue may be
