If you go to
https://www.warmane.com/devlog You'll find that it says, and I quote:
"Heads up about certain client modifications
October 9, 2019
We have been improving our anticheat lately, while no specifics will be given. We wish to inform players that we will no longer allow edits of maps. We have been logging terrain edits for quite a while and have seen a number of players having these altered, some giving an unfair advantage. Starting this week we will move these checks from logging only to kicking so everyone can get rid of these illicit client modifications."
I'd lurk around on the forums or wait for an answer from somebody qualified before making any modifications to the client.
