To make it short: I will have a look on this this evening, but yes... you would have to copy the lootspawn-logic from the static-crashsites to the new dynamic crashsites... the "animation" before the crashsite spawns has no impact on the actual lootspawn-system, i only changed the radius of the lootspawn to make sure nothing is laying under the wreck and let it look more realistic.
Thanks Grafzahl. I can't get it to work but I'm super stoked about everything you've made this far. Looking forward to future updates!
