do you mean an ipmi bug on all 13 servers at the same time ?
(I also have 2 supermicro servers in this cluster, but they use same ipmi watchdog driver. (ipmi_watchdog)
I had same kind of with bug once (when stopping a server), on another cluster, 6 months ago.
This was without HA, but different version of corosync, and that time, I was really seeing quorum split in the corosync logs of the servers.
I'll try to reproduce with a virtual cluster with 14 nodes (don't have enough hardware)
Could I be a bug in proxmox HA code, where watchdog is not resetted by LRM anymore?

But the pve logs look ok, and there is no indication
that we stopped updating the watchdog. So why did the
watchdog trigger? Maybe an IPMI bug?
