[Bug] When removing machines with wrench, they sometimes get downgraded.

Wait downgrade?

Afaik there are supposed to turn straight into machine blocks unless that was changed recently?

Not-A-Bug

The drop rates for machines didn't change, if they did I'd inform in the changelog.

So what you're saying is that i can not easily move my machines even with a wrench, and always have a chance of them getting downgraded?

Usage
To use the Wrench to remove a machine, simply right-click the machine.
The Wrench's removing mechanic will override the machine's interface-- don't hold a wrench when you want to use your machines!

Without the Superwrench 100% mod; there is a chance (Aprox 70-90%
success rate) that when you do, the machine will not be successfully
removed and instead you'll be left with a gutted Machine.

It's also worth noting that any items or energy stored in the machine will be lost when it is dismounted.
Shift/sneek clicking will move the output / selected face of transformers to the opposite side.

It is also worth noting that Electric Wrench has a mode which has 100% machine droprate but takes 3/4 of its power with one shot, if I remember correctly.

It actually takes all the power of a fully charged wrench, the mode is intended to be used with a lappack.
