The bug error report is what I posted there on the post #2125](https://forums.unrealengine.com/community/work-in-progress/38674-dungeon-architect?p=1486136#post1486136) from other user aswell I posted on the Haste plugin thread too the same, the log don’t say nothing more at all, the engine just crash at open if you don’t set that config I set crash at 90% of load ± and return that sentence in the bug report window. Is not related with other plugins as only happen with your plugins even if are the only ones on the engine, related cause are the only plugins I got that add tabs. Always happen on custom engine versions from Github any version from 4.9 to 4.18 will return this problem on Windows 7 Ult.
If you set what I changed then works fine.
To me looks like at the engine read the tabs for the tools at top left where your plugins add a new one, try to catch your tab id or count it but isn’t loaded yet or something rare happen but counts 1 more in the array than the actual ones that are loaded into the array at the launch.
