Hi Luke,
can you please describe which nodes are connected to the LAN and which are not? You say "one is connected to LAN" and the others are "operating as an access point", does that mean they are not connected to the same LAN via Ethernet?
If multiple nodes are connected and bridged to the same LAN, bridge loop avoidance should be enabled - you have that in your config, but you could double check with "batctl bl" and then "batctl bbt"/"batctl cl" (please post these tables if you think this could be connected).
You could also try disabling distributed arp table and multicast mode, just to make sure this is not shooting us in the foot here. Those optimizations are not really needed for such a small network.
Cheers, Simon

Running batctl 2020.1-openwrt-1 [batman-adv: 2020.1-openwrt-2]
When running a two node network with one node connected to my lan and the other operating as an access point, my network works great. I can connect clients to my batman nodes and access my LAN.
When booting up a third node. My network works for 1 minute, then breaks down. My LAN cannot ping any of the batman nodes anymore.
I keep receiving messages like this: "[ 2900.755655] br-lan: received packet on bat0 with own address as source address (addr:8c:ae:4c:db:14:5c, vlan:0)" which signifies a bridge loop I think.
My originator messages look wrong as I can see my host originator messages along with all the neigbor nodes:
