I think this issue originates in the Mantle, where Iris is both reading from and writing to a matter slice (tectonic plate) at the same time, because the chunk is generated and immediately unloaded by the RTP plugin.
This issue ought to be resolved by the person who designed the system hint hint, since this involves a lot of the core mechanics.
I wrote a bandaid fix in #963 but this can use some more attention (since the tectonic plates are deleted & rewritten).
