TCR Tekkit Classic Reborn issue

I am playing a TCR server but the repair power of the Repair Talisman, and the high covalence dust, are locked. I'd like to know how can I unlock them, because that is fundamental for the tests I wish to do in my server.

Not as far as I know, I tried my best but I didn't find anything specific. Seem that the creators of the modpack for servers managed to lock every "OP" exploit of projectE, but without worrying about people who didn't want it. I just joined their Discord for further investigation, I'll keep this thread updated as soon as I find something certain.

Ok. It turned out that the original creator of the modpack tried to balance the experience by blocking the exploits. Even though, now that TCR 2.0 is out they do not support TCR 1 anymore. So please, if you can, update the old TCR 1.7.5 to the new TCR 2.0 (I will make a modpack request if needed).
