Update:
Managed to replace the file (flora.tpac) that had gotten corrupted by upgrading to 1.7.1
This solved the issue that I had experienced.
ps: Not sure why, but my upgrading to 1.7.1 somehow corrupted this file and also reintroduced the issue of Steam not closing the game properly when exiting the game
