I was playing around with your mod in 2.1, and I decided to build a power plant using obelisks, i.e., before the fusion version.
However, when I tried to power them with the appropriate fuel, i.e., 4th stage extreme energy, the thermal obelisks showed that they were low on power (Low Power). Even though, theoretically, they shouldn't consume any energy.
And when I tried installing a pure energy obelisk, which immediately converts this fuel into energy, not only did its texture not load, but the obelisk itself also returned an error: "Input fluid too cold"
This is pure softlock, as the game didn't throw any errors in the code. Game version: 2.1.23

i see, its a problem with UMR and the last fluid fix, i will take a look, ty for the report

so i tested UMR alone and its working, send me a pm in discord. The electric one sprite is indeed broken

thats proly some mod-mod thing

What is your Discord tag?

I figured out what the problem was. It turns out the obelisks aren't accepting cold 4th-stage extreme energy anymore. It needs to be heated, according to your new mechanics. After I applied it at 640°C, everything worked instantly. I'll be honest: Smart. Very smart. So, to build a proper power plant, you need to build a processing plant on Nauvis, then build a proper space line to ship the cells en masse, and only then, somewhere on Vulcanus, build a power plant with 50 GW capacity
But the sprite on the electric obelisk was fixed, thanks.

you can send the fluid over planets, but you need to heat it again, the UMR core is dangerous in some planets, specially vulcanus

Now, if I play with your mod, it will be easier for me to build a power plant on Vulcanus, locally produce shitton rocket fuel (since thermonuclear is not immediately available), and locally drop uranium cells/uranium-235 onto the planet, since 238 can be produced directly on Vulcanus (don't ask how), and that's how to make fuel
