Using itemrack to swap weapons in combat fails because of a "protected function".

In the brief digging I did PickupContainerItem() does not look to be protected but there are some docs about calling it twice in the same tick causing the client issues. See: https://wowwiki.fandom.com/wiki/API_PickupContainerItem

There are rumors that it is a protected function in classic but I was not able to investigate this.
Can you have a look if you can add a delay between the calls and it might be fixable?

Retest with 3.15.

Perhaps the bug should be fixed rather than outright removing the feature entirely. Additionally, to answer your question, no, PickupContainerItem(...) is not a protected function.

See discussion in #28
I guess the documentation is not up to date.
I also tried adding delays between the pickup calls or trying autoequipitem() but it also does not work
