Wow thank you! Now please take a deep breath and try to control your panic good sir! Your stuff looks really cool and I'm sorry it broke on beta software but try to remain calm and keep things in perspective. Rest assured, we worked really hard on this and we care and we are working on it. It's a hard bug to repro and so far you are the only one who has posted about it.

Here's what we have so far:

There is a semi-reproducible Pri-0 bug/showstopper native to Driftwood where users can fall through the floor on teleport or on level start- this will most-likely be fixed in the next release.

There is a less serious issue where animated dynamic actors like the ceiling fan, windmills, and wildlife will stop animating or disappear completely on saves that are reloaded. Not sure how this is progressing.

Then there is the save-file issue you are having where the entire file becomes corrupted (which may be related to the previous issue.) We have still not been able to reproduce this issue so it's taken some time.

Here's how you can help: Take a few minutes and post your full system hardware and OS spec including exact driver versions of everything so we can try to repro on a similar system here. Are you running on a Vive or a Rift? Are you using the standard controllers? You get the gist.

Again, we care and are doing the best we can but help us help you :)
