Oh dear Ruth, not a good day
With the fleece wrap, I imagine that the nappy got soaked (drinking more? need extra boosting?) and it wicked through the fleece wrap onto his clothes and gro bag. Fleece allows moisture through but dries extremely quickly (hence fleece liners). I found tots bots fleece wraps worked very well at night (I used them before switching to wool) but only if the nappy was really well boosted. Perhaps you could add in more tonight? - something slim like hemp would work well - make sure it's had plenty of washes though so it's reached full absorbancy.
If Swaddlebees and HH normally work well for you I don't really know why they didn't today - unless he had been drinking more and so peeing more? Sometimes I find a reliable nappy can leak with Matthew if he's either been in the same position for a long time (like in the car) or the opposite - he's squirming and wriggling around so much that the pee manages to find a way out!
No real advice apart from trying more boosting, I hope it's just been one of those days and your nappies are back to being reliable tomorrow.
I hope your DF's eye is ok and you hear from him soon.
Sorry it's been such a bad day so far, sending you a hug!
