I am using ArcGIS 10.6. I have used the Spatial Join tool many times in the previous version (ArcGIS 10.4), without any problem. This is the first time I use it in this version. After doing the job and claiming the spatial join was successfully done, it turns out that no feature class has been created. When I try again, curiously, the new feature class seems to be named nameofthefeatureclass_2, thus suggesting nameofthefeatureclass_1 indeed exists somewhere.
Am I doing something wrong?
PS: sorry for my English...
