A bit thrown by this one, 'specially since the exact same lines worked peach-keen in a parallel process common event.

I'm setting up save points, and that a bedroll or tent must be used either there or on the overworld map.  The trouble comes when the item permissions when approaching or stepping on the save point.

Maybe what I've punched up would be helpful in diagnosing what the crap went awry.  Having it recognize map types is going without a hitch, using this script (my apologies for the lack comments).

I had a common event set up to handle what items should be allowed to work on which map, as well as an exit spell (courtesy of Hime's Warp Stone script: http://forums.rpgmakerweb.com/index.php?/topic/4065-warp-stone/), and all of this seemed to work fine, too.  Switched out tags on the maps, and things were going okay.  That script:

Now this was where the trouble came: setting up the save point.  I placed events around the save point with the script, so that the bedroll and tent couldn't be used off the save point:

$game_items[33].occasion = 3

$game_items[34].occasion = 3

And this on the save point itself, so that they could be:

$game_items[33].occasion = 2

$game_items[34].occasion = 2

EDIT: I should specify, both sets of lines were set in common events, that were called for by a step-on triggered event.

And while these lines were there, it threw me this error.

I'm confused; the exact same lines worked fine in the common parallel process.  Does anybody know what went awry?
