Please post what a log.
1 and 4 should be fixed when v9.9 goes live, just pushed it.
As for the wilderness gate handling you will need to have the pop-up box disabled, the bot does not currently support handling the warning message. This is because during testing of it the bot was not reliably able to handle it prior to being attacked by a skeleton, this would cause a potentially endless loop resulting in death.
As for the bugging out on death, that one I will need logger info to troubleshoot, I just checked death handling and it worked fine for me. To access the log simply click the settings button on the bot and select toggle logger.
You have one now.
