[4.7.3] Crash if Unique Name field of Create Instance (level streaming) has a space

When creating an instance of a streaming level using Create Instance blueprint node, if you put a string that contains a space in Unique Name field, editor will crash upon pressing Play.

Hi JParent,

Thanks for your report! I was able to reproduce this in 4.7.3, but it appears to have been fixed internally. fix should be included with 4.7.4 once that is released. Thanks!
