Hi , So the code above shows how I am spawning it if thats what you are asking.
I was able to reproduce this in a new code project based on 4.13.2. Here is a link to the project Dropbox - PhysicsBug.zip - Simplify your life
Note the code is a bit silly in places but its just copied from our actual project and then heavily edited to just work.
If you load the TestMap you can press mouse button to spam pots.
You will notice some of them will stop right infront of you and just drop
The static mesh on that throw object is set to overlap everything with simulate physics on. This case is using the projectile movement, although the code for the alternative is there too just in case.
There is logging too…
Note this only happens every now and again, sometimes it happens multiple times in a row, sometimes one in 20 to 30…
Some more info: It seems to happen more if you run with slomo 0.2, it is suddenly a lot more common. I assume its colliding with the player character but without any block , stop or hit events happening.
