I am using Just Enough Dimensions to create a wasteland dimension that you spawn in when the game first starts. You don't go to the overworld until later. Something in the process of generating this dimension, spawning the player in it, and having the Recurrent Complex building spawn there as well, is not working consistently. It is very intermittent. About 60% of the time the structure will spawn, and with no changes made, it will choose not to spawn the next time a world is generated. It results in me just starting new worlds until, for some reason, on one of the attempts, the structure decides to spawn in. Any ideas what could be the issue?

I also notice that there is no message indicating the number of structures loaded upon login, whenever the static structure is missing.

Any possibility you are gonna respond to this any time soon, or should I just give up all hope?

Does this happen on specific runs or is it per-world? On the runs where it doesn't happen, does the log show Recurrent Complex loading and doing stuff? Also try doing /#sanity on those where it doesn't work.

It happens about 30% of the time I generate a new world. I really do appreciate you getting back to me, I know school can be a handful. Unfortunately, I JUST finally found a way to spawn my structures using structure blocks and the World Primer mod. So while I do hope you will be able to find out what is causing this issue, I have found a solution for my particular situation. Thank you though.
