Yes, it is the end of an era. Cricket and Fern are working diligently to transfer all the ZA ZT1 downloads here, and the ZT2 content will be hosted by ZooBerry and Goosifer. It will take some time to get everything squared away, so thanks everyone for your patience.
New version of the file has been submitted. As well as addressing the NameID/HelpID and unlock file issues, I have also added graphics and tested proper functionality for deteriorated and destroyed fence states for the exhibit fences.
(btw: I ended up deciding to use the IDs of the plexiglass and concrete exhibit fences as a compromise to make them show correct strength/climbability tooltip info. The decorative fences use the IDs of the decorative picket fence, which is close enough.)
