Hi, thanks for the report, you're AI report is not entirely accurate.
For starters, my plugin is not responsible for spawning Bradley crates, it merely sets the number of crates to spawn when it dies. The native Rust code spawns the crates.
You are correct, the crates are somehow falling below the map. This is happening depending on where the Bradley is spawned and the terrain around it. Native Rust Bradley only spawns in Launch Site, which is flat terrain. When the Bradley dies the crates spawn without issue on the flat ground.
You are not alone in seeing this happen, although it always used to be rare. In a future update I will take over the spawning of crates so that this cannot happen. It wont be out for a little while, but will be ASAP>
