Mine did about a week ago. There's a chance it was your o ring, check the stainless line going into your bellhousing for fluid. Otherwise, it was probably your slave. Mine got caught on my shift fingers somehow... tore apart the slave, bearings fell out of the slave into my starter and ruined it too lol. Your clutch may or may not have been ruined by the fluid getting on it, mine was about to go anyway so I'm ordering a replacement today.
That's what happened to me anyway.
