Hi eliont, looks like EI / SE's beacon overloading does not work. The machines still work though the icon shows they are overloaded. I have tested beacons from EI, vanilla, and SE.

(plus alien beacons from EI)

EI lab would be disabled but assembling machine 2 wont be. I guess assembling macine 2 exists both in, and controlled by, EI and SE and the two beacon mechanism conflict.

Better report on Ei discord, compat mod did not touch beacons in any way.

Update. Sorry, after further testing I found it is caused by using another mod, Crafting Combinator. Only machine controlled by crafting combinator will bypass overloading. So this is not a big problem anymore as I only use it in my auto-supermarket. Removing that mod also solve the problem.
