Chain link gates why no work?

Found an abandoned shopping plaza. Typical entryway. I believe 7 chaingates wide for an entryway. But I figured it’d be better to widen it. So I decided to bash a connecting fence and replace it with a gate, but I was unable. Went to the jsons for construction and couldn’t find anything besides check_support to identify specific requirements. Couldn’t figure out where that was to modify it.

There are 5 builds a day, so you better report game version you are on.

Hnnggg…already put my comp up for the night. I suppose any definite answer can wait a bit.
