I'm not sure how you build your maps but the new skate park PoI is located
<decoration type="model" name="skate_park_01" position="-1325, 62, -1123" rotation="0" />
The terrain of b94 seems to have changed a few areas, so this may not help, but if I'm wrong, I hope this saves you a minute of xml searching to add it. Thanks for your work, Curbolt.
