Pump next to water, connect pipes to pump, pipes run next to your farm plot blocks/hoe'd ground as a water replacement. It can take a while for the system to "fill" up, just FYI. Supplies water to at least 2 blocks, but might be 3 (dont remember off the top of my head)
And yes, it does check it's next to water.

No electricity needed.
Not a lot I can do about the screamer thing. Lots of zombies = lots of FPS loss. Anything over 50 zombies is gonna kill your FPS.
Still dont get what you mean on the animal snare. It triggers, you loot it, you reset it with the animal feed and then you have to wait for it to "trigger" again. That's intended to stop people spamming them for meat.
Will look into the hazmat jacket but that shouldn't be happening.
*ahem*

That's at the bottom of the titanium machete code in items.xml. You can check it for yourself. So... yes... it does have it's sneak damage.
And the turret... okay? If you're having this many FPS issues then you're gonna have to post your PC specs as it sounds like you may need an upgrade tbh.
They work fine. People in my discord have been downloading from both and the gitlab link is used by the launcher... had no complaints from folk on that either.
If you can't download from either of those sources, you may need to check your internet.
