Map save taking a long time

Hello,

My map has a simple 7x7 terrain, 2 ai characters, and eqs testing pawn and a skylight - yet it takes upwards of 5 minutes to save…
it loads very quickly, map check reports 0 errors.

My hard drive has heaps of space so there’s no issues there either…

It only seems to happen on the actual map, blueprints save no problem - its just the map.

Something I have noticed is in the autosave… it jumped from 582kb to 12.8mb to 81.9mb to 223mb, something is storing ALOT of data… will investigate further

latest save in output

Cmd: OBJ SAVEPACKAGE PACKAGE="/Game/A_RTS/Map/testMap" FILE="…/…/…/…/…/…/ 4.12/Content/A_RTS/Map/testMap.umap" SILENT=true AUTOSAVING=false KEEPDIRTY=false

LogSavePackage:Display: Finished SavePackage …/…/…/…/…/…/ 4.12/Content/A_RTS/Map/testMap.umap

output log was massive - cleared it, doesnt affect save speed at all… lighting build time is about 1 second, its a very clear scene

it fixed itself…

I’m having this exact same issue. Do you have any idea how you fixed it?
