Hello there! Sorry guys you have so many issues with service rooms. As far as I can see it’s mainly caused by one small detail mentioned by Hanway Lin (thanks man for touch btw!) - I have never ever made 4.8 version of service rooms 
It should be listed 4.9 only. My older packages are 4.8 + 4.9 compatible, but sci fi one was created with 4.9 only. I think epic could put it for 4.8 too as it’s possible “sometimes somehow” to run it with 4.8, but it’s not official thing and it doesnt work “out of the box” this way. I will try to port it for 4.8 and if I will succeed I’ll post details here.
