Trigger can't find table

We have a Percona server replicating to a MeriaDB server like follows:

Server A (Percona 5.6.32-78.1-log)

Table A – (trigger inserts record, after update) --> Table B

Server B (10.3.9-MariaDB-debug-log)

Table A (replication from server A OK)
Table B (replication from server A OK)

If a trigger is added on Table A - triggers work OK
If a trigger is added on Table B - assertion fails in sql_trigger.cc line 2192

For our particular use case we added a trigger (after insert) on Server B::Table B to insert a record into ServerB::Table C

Outside of a debug build replication breaks with the error message; can't find `Server B.Table C`

I have attached out error log and output from gdb.

Hope this is enough information, happy to provide more if needed.

Edit: Replication is ROW based with slave_run_triggers_for_rbr enabled

Thanks Martin
