    I'm hitting this as well, and it's causing problems for some code that's trying to interop with a native plugin. The plugin properly fills a System.Numerics.Vector3[] buffer using a stride of 12 bytes, but the script code running in 2018.4.6 accesses it with a stride of 16 bytes, which obviously doesn't work as intended. When can this be patched in 2018.4?

    PS- We've been discussing this over on an unrelated GitHub issue here:
