Steam Redownloaded Kotor 2 After TSLRCM Install?

[Skeet1983]

Hi guys. Early this morning I installed Kotor 2, followed by TSL RCM version 1.8.6(?). Everything seemed fine, but this morning after rebooting my laptop, I noticed Steam downloaded files for Kotor 2, and it was around 3GB, or it seemed to be downloading files for Kotor 2. Total game size on my SSD is a little over 4GB. Anyway, I played game a little bit after the supposed update, and TSL RCM still seems to be installed and working. Should I be concerned about the update that may have happened? Help GREATLY appreciated
