I have other mods that generate their own kind of map like Quark and BOP and with those it does not happen so I imagine it will be something that might be interfering directly with this mod.

Whenever I enter a save with a generated map from the list of available themes, every 30 seconds, ish, I get a ticklag (it may have another name but I don't have a better expression) of about 5, 7 seconds where the game stops all together. And in the pause menu happens too.

I have already tried to generate the map as soon as I enter with the /forge gen command to see if it improves and nothing. I tried to take out other mods that interfere with the map as the Recurrent Complex and nothing. I've tested all kinds of themes and it's the same, even in those bubbles that don't spawn anything else.

I have arguments in the launcher for the garbage collection and these work quite well on the other map types. I have enough RAM to run the game at a stable 30 to 50 depending on the sites and quantity of machines. (4 of 8 allocated - 130ish mods)

Has anyone else gone through the same or do you have any ideas that I can test to see if it improves? I use Optifine and have not tried without yet, maybe it's important but without it I do not usually have frames above 30 anyway.

Thanks.
