Like i wrote on forums already, and also to few people, who were asking about compatibility with my mod.
SX is mod in development, it's hardly a month out (actually somewhere around 6 weeks since first version), people should not expect other mods to start making compatibility patches with mod, that has not reached stable phase. (he uploads even multiple versions during single day).
If anything people should ask for compatibility patches Earendel, not other way around.
For now he already marked some mods incompatible, because doesn't plan to fix compatibility in near future (no rso is not one of them).
I will wait, until cadence of SX releases settles around 1 or 2 versions per week, they i will start fixing compatibility and IMHO that should do all mod developers, that plan to be compatible with SX.
