Thank you all so very much. In 24 hours I had 54 responses, probably 3 times what I was expecting. I loved all the positive comments in there as well, so thank you all for those as well. Not everybody chose an option, or variation of an option, just gave me lovely comments.
I had 2 people tell me to do what was easiest or best for me. I'm taking this as option 1!
1 vote for option 1, just lose the chapter.
19 votes for option 2, insert a new chapter and renumber.
14 votes for what I'm calling option 2a, which means insert a chapter 12a. (I'll have to check with Lazeez how this is done).
8 votes for option 3, insert it as a new chapter 34 and put some sort of comment in to say it should have gone earlier.
4 votes for (a sort of option 4!) tagging onto the start of chapter 12 (Or maybe 13)
I also had 7 people just telling me how much they were enjoying the story, without offering an option.
It's obvious most of you want to see the missing chapter, and most want it in the correct place. So that's what I'm going to do.
My next task is to finish it off as it is, and then decide whether to tag it onto 12 or 13, or whether to insert it as a new chapter. That partially depends upon how long it ends up being. I'll contact Lazeez when I'm ready to post, to determine how easy it is to insert a 12a, but a few people have suggested I repost the other chapters anyway to include all the tweaks and corrections I have done at the same time. If I'm doing this, then I might as well create a new 12, and renumber the rest, but I'll make a final decision closer to the time.
One thing I'd also like to say is that the main reason for the slow rate of posting is that the last five chapters (currently 45-49) are not yet complete. 45 probably just needs to be reviewed by the Swarm team, 46 and 47 are close but do need work, and 48 is still a way off. 49, technically is complete, but I'm classing it as incomplete in case it needs to change because of anything I do in 48.
Finally, thank you all very very much for the kind words and encouragement. It means a lot to me.
