CSGO will correct the player crash when changing the map. I do not give a 100% guarantee.
Install
smx file move to csgo/addons/sourcemod/plugins/
Use
Now supported !sm_map
Now supported !sm_admin map change
Use mapchooser ( optional )
!changenextmap mapname and !mapend
the map changes automatically at the end of the round.
Important Note: If you are looking for the full solution, do the following.(Maybe may not be the definitive solution)
Make your maps in HDR based on some descriptions from the community and my own observations.
.smx
