Property Editor or PRED

HI Bones, Thinking about That "Testing PRED" message you observed.

It might refer to development tools collectively known as PRED, standing for Pr operty Ed itor,

It gives a way for developers to look inside some files (on your gadget) and edit or adjust the properties. It is possible that TV was Testing the Use of a new "Property Editor".

I would say it did not competely work as intended if that is the case.

This seems more likely, that that this was the name of the new pterodactyl.
