If Maradino's Ghost gets muted, he may try to call his allies, anyway, leading to a quick succession of his banters (multiple within a second) while failing his spells and finally after several seconds his turn ending without any action. --- My (PC) co-op partner regularly (but not always) looses his equipped gear on his client when loading a new session or switching areas, quicksave-quickload usually solves this issue as a workaround. Additionally, while all characters have full health on my client, his client sometimes shows them as missing some HP (maybe due to bonus health by gear).
