Hello, I am facing the same issue of UE crashing while rebooting when using an alembic geometry cache in the level. I get the same error saying that ‘The file is most likely corrupt’ Any help would be appreciated. Thanks in advance! ---

@Adrien @ Do either of you have a test asset that can reliably reproduce this issue that you can provide? If so I can test on my end and report if I’m seeing the same crash. I didn’t find anything in our system that would indicate this issue was reported already. Thanks! Tim ---

@Tim Hobson Thanks for replying, for the time being I was able to get the file in question, which contains about 30 tracks into 3 smaller cache files with 10 tracks each…this way UE loads them up correctly on reboot. Would have been great if we could have the larger file working correctly. I can send you the file only by Tuesday since i am travelling at the moment. Thanks again ! ---

@Tim Hobson Very sorry for the dealy…,Here is a link to the file I was talking about. I’ve been using UE version 4.14.0. [https://drive.google.com/file/d/0B4cNiwzMjRSsNlhLb3R0LUJycHc/view?usp=sharing](https://drive.google.com/file/d/0B4cNiwzMjRSsNlhLb3R0LUJycHc/view?usp=sharing) Thanks ---

Hi , Thanks for posting back! I was able to get the crash and submitted a ticket here: [Unreal Engine Issues and Bug Tracker (UE-39946)](https://issues.unrealengine.com/issue/UE-39946) Hopefully, we can get this resolved soon! Tim ---
