Need help finding an unintended overwrite

I've confirmed that 'lua_proc_handle_prep_scan' (called by 'lua_proc_handle_dump' and 'lua_proc_handle_bytescan') indeed receives the correct range but sometime between there and attempting to start dumping the memory (which somehow ends abrubtly) the values are overwritten to 0 and no percentage of the dump/scan can be calculated

Full project is here:

The mentioned functions and the related calls they make are mainly in lua_process.c and proc.c

I gotta start preparing for work so any further replies I make until I get home tonight will be on my phone.

Managed to fix it, mishandled the return values of 2 different functions which prevented the scan from being done in the 1st place, so not overwritten, just never filled to begin with

Edit: Forgot to link the updated code
