I have noticed 2 problems with this mod that makes me unable to use it.
1) If i place a lot of concrete the bots will lock themself up by requesting more items then there can fit in their inventory, so they all just stands there.
2) I have a construction job, one missing lap on my railway track to an outer base, 4 robots has self destructed by pathing right though 20 mobs hives. I have 1 left but every time i place it will go there right away.

Also are there a way to downgrade the Construction spiders back to a normal spider?

I also use them a lot for laying concrete (we're talking about roughly 40k-60k at a time, and I haven't had the issue you've described. What I've seen is them hang out for a long time (because the available material is being split between many constructions), but eventually, they all went and did their thing. It just took a while. I try and look at this mod not so much for instant building, but rather for things that are less important and might take a while. In other words, if I need a rail setup, for example, I do that by hand or with onboard bots (unless I don't care how long it takes).

I believe the issue occurs if a chunk is split but is not fully built. I have a fix that will mostly avoid this by having the last split job scan for completion in the next update.

I have the same problem 1 as the original Poster: spidertron requesting 10k landfill while it can only store up to 8k (minus construction bots).

Just to be safe, is it a good idea to put a cap on total requested resource (stack) to be < 80 minus construction bot (and maybe minus 5 extra slot to be absolutely safe) ?
