Where does one get the 1.50 DL link haha I also have that issue with 1.53I narrowed it down to one thing: When using the newest version of your mod (1.5.3), the Distributor and the Electrics unscrew and fall off. When trying to attach them back, there is no check mark, so I am unable to do so.
I also noticed that when using the older versions (1.5.0 - 1.5.2), I can't find the items in the shop.
