Some filter lists cause Orion to crash when updating them (Settings -> Privacy -> Update Now). Currently, the ones I've tested that cause this are Fanboy's Annoyance (the new built-in one which can be selected) and OISD (https://big.oisd.nl/). I think other custom filter lists cause the same error, as the only instance where updating worked without crashing was when only EasyList and EasyPrivacy (those enabled by default) where enabled.
