I definitely remember more than one temple being sacked and people started to ask Veleno why nothing was being done about it, which is what lead her to poking Galiard about adding in the bit about not destroying temples into one of the treaties with Ohnar West. There was also some shouting about priests being arrested, beaten up, tortured, etc.
As for what Arcachon did, I've no idea, I'm part of Ohnar West so I can't say if they did or didn't do something. It wouldn't surprise me if they did burn temples though, there's a pretty deep hatred for the Sartanians and their church.
