VR Expansion Plugin

Ah there we go, thanks for the log it gives me what I needed.

When you updated to the 4.18 version of the plugin you must have just dragged the files in to the folder, you should have deleted the current contents first. GripSteamVRTrackedDevice was not overwritten with a new version for 4.18 because it has been removed entirely from the plugin (is no longer required).

You can feel free to just delete the GripSteamVRTrackedDevice.cpp and GripSteamVRTrackedDevice.h files, but I would suggest that you delete everything and re-copy the files in to make sure nothing else is left as its legacy version.
