Also my migration steps from D2R GoMule v2.6 to v2.7:
* backup "T:\D2_Game_Data\GoMule_2.6_D2R_Data" ==> "__backup of__GoMule_2.6_D2R_Data__2025-1-26"
* create "T:\D2_Game_Data\GoMule_2.7_D2R_Data"
* extract the v2.7 zip file into ==> "T:\D2_Game_Data\GoMule_2.7_D2R_Data"
* had to go into ""T:\D2_Game_Data\GoMule_2.6_D2R_Data\GoMule" and move the folder contents one directory up and delete the "GoMule" folder
* copy the projects folder from "T:\D2_Game_Data\GoMule_2.6_D2R_Data" ==> "T:\D2_Game_Data\GoMule_2.7_D2R_Data"
* backup the D2R GoMule v2.6 stashes folder "T:\D2_Game_Data\v1.06_D2R_Restart\D2R_2.6_ATMA_Data" ==> "T:\D2_Game_Data\v1.06_D2R_Restart\D2R_ATMA_Data_Backups\2025-1-26_D2R_2.6_ATMA_Data"
* copy "T:\D2_Game_Data\v1.06_D2R_Restart\D2R_2.6_ATMA_Data" ==> "T:\D2_Game_Data\v1.06_D2R_Restart\D2R_2.7_ATMA_Data"
* backup the "projects.properties" file in the projects folder to "__backup of_projects.properties_on_2025-1-26"
* edit the "projects.properties" file to change the paths from "...\D2R_2.6_ATMA_Data" ==> \D2R_2.7_ATMA_Data" (preserving the double back slashes in the path strings of course)
I created a new shortcut "D2R$_GoMule_2.7" with:
* Target = "T:\D2_Game_Data\GoMule_2.7_D2R_Data\GoMule.jar"
* Start In = "T:\D2_Game_Data\GoMule_2.7_D2R_Data"
I opened multiple char files and the shared stash, which opened without errors initially but after opening many more char files and stashes, and doing and open/close several times on the same stashes the UI started to glitch again. I closed the app and open the items again and the glitching had stopped. I then closed all the open items in GoMule, exited GoMule, ran D2R, entered into 1 character, opened his inventory, accessed the stash, and exited the game. I was then able to open and interact with the shared stash and the character file in GoMule. All seems to be well.
Thank you m4ke, Silopen, and everyone else.. I'm not wondering if my installed version of Java is the problem as far as the glitching UI is concerned.
