Chaos Trial Savepoint / Re-enter

On multiple occasions have I lost a run of trial of chaos due to an unexpected disconnection, sudden crash of the client ,etc. This is very maddening as I have literally lost multiple exalt/divine's worth of soul cores and rewards from any other previously mentioned mishaps occurring. Trial of the Sehkemas I have literally dced in the middle of a boss fight and am able to come back to the start of the room to continue. PLZ resolve this.
