Error in Follower (misc.js #1621) unit.fname is undefined

[Danmanjo]

Randomly MFing and keep getting these errors across multiple keys on the same client, causing the bot to leave the game and wait in lobby until new game is created. This is mostly happening in the middle of MFing. It only started doing this today. Never edited nor opened misc.js so I know I didn't accidently change anything from the file.

Line 1621 is below.

let name = unit.fname.split("\n").reverse().join(" ").replace(/ÿc[0-9!"+<:;.*]|/|\/g, "").trim();

I confirmed that the information in that line is in the original kolbot file when I extracted, confirming that I never opened or changed the file.

Any suggestions to what unit.fname. is referencing and why it is randomly now coming back as undefined?

Thank you
