Error:

Assertion failed: Package->IsFullyLoaded() [File:D:\Build\++UE4+Release-4.14+Compile\Sync\Engine\Source\Runtime\Engine\Private\PackageMapClient.cpp] [Line: 2405]

When i press PLAY in editor, editor is crashing. What i could find:

  1. If variable CraftList is not replicated all works fine.
  2. With some variation of data in DataTable all works, but not stable. I cant find which type of data is crashing editor. I try delete some icons and 2 times game started at 3-rd crash. With class type same result.

What i’m doing wrong?)
P.S. Sorry for my english.

Please add a crash log. Also move the topic to Bug reports (that let Epic Staff notice the post).

How to find crash logs: A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums

Problem i fix, don’t ask how, i dont know. Magic, sacrifice and dancing with previous version. But i cant find crash log, specified adress in wiki is empty on my pc. May be i must set flag somewhere for generating this log?

Fixed, but i cant explane how)
