For the last 12 years, if a gate was locked, it could not be dismantled with the use of tools, but now it can. This has caused many issues for me and for many of the servers im in, and the ones i moderate. it leaves bases more vulerable, such as if a gate is built on the second or higher floor of a building, it can be dismantled from the bottom even if it's locked (if it sticks out, which it usually does in most buildings). or building any sort of base that doesn't have the inside of gates completely isolated becomes useless. I hope this is a mistake and it'll be fixed soon, otherwise it'll make base building a moderate amount more tricky and less creative.

build a gate, lock it with a electronic lock or a 4/3 digit mechanical lock, grab a hand axe, dismantle it from the back
