After the update, some effects (smokes for example), stopped working when they have a high "Y" value. Before 1.28 I had some smoke that was ~150 off the ground as beacons but after the update they stopped working.
This was first noticed on a console server but after local testing on my PC it does the same thing.
1 Add a new area in the cfgEffectArea file and setup your effects (only tried with M18 smoke effect (smoke_M18_green_02)). 2 Change the second "pos" value (Y value) to something positive (best to try 20 or higher since with the value set at 10 it worked but it was still on the ground). 3 Start server and check.
I also tried this with both new and old cfgEffectArea.json (pre 1.28 formatting and 1.28 formatting) config and with some other smoke effects. They stop working if you set the height to more than 20.
