Describe the Bug

A campaign with an add-on embedded will generate an error on the add-on's onInit, if the event requires campaign resources, like switching to a lobby map, reading images from a table etc.

According to Skullman3194 (on the Discord), it appears that MT attempts to execute the add-on code before it has actually load the campaign resources.

If I defer the onInit code that requires these resources, i.e. use the execLink(link, 1, "self") function, my initialization code works.

To Reproduce

1. Create a campaign.
2. Create a second map.
3. Create an add-on which attempts to switch to second map in onInit.
4. Save campaign.
5. Restart MapTool and load campaign.
6. Observe failure.

Expected Behaviour

I expect the add-on to be able to load campaign resources in the initialization code, just like a library token.
Without having to resort to deferring code.
