Hello everyone, I'm still new to SolidWorks and I'm pretty stuck right now.

I want the piston rod to be able to move forwards and backwards, in the subassembly, cylinder assembly, I put a limit and concentric mate and it works as expected there, but in the main assembly it doesn't.
I've turned the assembly flexible and I've made sure I don't have any dependancies attached to the rod and it won't budge. Any idea how to fix this?

Also this assembly seems to break very easily, sometimes a bunch of errors show up for no apparent reason, I restart it and then it works like nothing happened. I'm not exactly sure what could be causing that. Any ideas?
