It seems that, at the range of ~500m, techs (specifically Auto-miners, here) can remain loaded in world and functional, e.g. spawning newly mined chunks. However, the resource chunks themselves are almost immediately unloaded from the world (or something occurs with that effect). The problem that this unloading range inconsistency creates is that very many resources end up stored in precisely the same physical space. So when player moves a little bit closer, they all get reloaded simultaneously to find themselves intersecting, and subsequently explode everywhere (if quite a lot have built up): (Save attached.) Context: I'd been reloading my saves from my last YouTube episode (filmed in 0.8.2), investigating how my auto-mining base had managed to make a (fairly wide spread) mess of resources on the ground, when there's no way that the auto-bricking base should have been overwhelmed by the max rate of 4 chunks every 10 seconds (from the 4 auto-miners there). I reconfigured the bricker and travelled back to my mesa base (500m away). The auto-bricker you see in the video and save is a broken design, unable to pick up more resources, it was unloaded from the game anyway. I stayed up at the mesa for the best part of an hour, fiddling with new bricker designs on the Rodite seam. Then when I returned (by 'fast travel'), the explosion occurred. Note it also happens if you fly back over, or inch back just inside loading range. It looks to me (having approached from different angles) that the resources explode out from the ground slightly down the slope from the auto-miners. Implying that they were allowed to roll away from them a little upon being spawned, living for ~1 second before being unloaded. I'd urge the range on this resource chunk unloading to be bumped up a little, in line with the maximum tech unloading range. I'm not sure of the span of ranges over which this glitch can occur (I didn't stay totally still up there, so I'd estimate it's at least 50m or so). A big area of probability, in a circle that size. The issue certainly seems likely to reoccur in the next episode I want to film (so potentially very problematic for me); I'm intending to focus on simultaneous auto-mining operations in multiple different, but adjacent, biomes, within a 500m radius, probably pushing up to this distance limit. It's not meant to be anything super clever, just playing the game as intended, trying to avoid creating resource lag-pools, or having to just leave the game afk at each mining base for hours, while resources slowly accumulate. Edit: I'm going to tag @Django, as he responded on a somewhat similar issue I reported previously (and he loves to be pestered about little technical issues ).
