# Helps fix: WARNING: Failed to load 32-bit libtinfo.so.5 or libncurses.so.5.

The guard if [ ! -f ... ] && [ ! -L ... ] skips the fix when libtinfo.so.5 exists as a broken symlink (-L true but target missing). Using an existence check like ! -e (or explicitly handling -L + ! -e) would let the script repair broken links and still avoid overwriting valid files.

The symlink creation can fail if ${HOME}/.steam/steamcmd does not exist yet (fresh install / before SteamCMD has run). Consider mkdir -p "${libtinfo32dir}" before ln, and capture exitcode=$? after ln so fn_fix_msg_end reports failures correctly.

This new libtinfo fix hard-codes ${HOME}/.steam/steamcmd, but elsewhere in this module SteamCMD artifacts are searched in multiple locations (e.g. ${steamcmddir} and ${HOME}/.local/share/Steam/steamcmd). To ensure the warning is actually resolved in all supported setups, consider applying the symlink fix to the active SteamCMD directory (or iterating through the same candidate directories used for steamclient.so).
