I just found out that the GI cache in Preorder Beta9 apparently can bloat very very fast. On a currently 450MB test Project the GI Cachces in the Project Library Folder (under: "GiCache") amounted to already 20GB. The GI Caches aren't cleared on deleting the lightmaps and aren't cleared on exiting Unity. Is this correct behaviour or is this a Bug (so should I report it)? Can I clean the GI Caches manually somehow? (edit) filed a bug report either way. If this happens on the boot drive this could be pretty lethal for the system.
