Body of AIML <condition> loop fails to execute in Pandorabots

I'm trying to loop through a list using AIML in Pandorabots, with the standard library, via MS Edge on an up-to-date Windows 11.

All of the following code occurs within the same <think> tags.

There's another loop immediately prior to this one. These two loops are functionally identical. Each loop references a different map of zero-based indices to predicate names, in order to set all the predicate values to "unknown".

The only difference is the two map files; the only difference between them is case and (trivial) string length, and they both work in other contexts:

[["0", "HI"], ["1", "BY"], ["2", "OK"], [ ... ]] and [["0", "hello"], ["1", "byenow"], ["2", "okay"], [ ... ]]

So the first loop works, but then this one does apparently nothing:

<set var="i">0</set>
<set var="allreset">FALSE</set>
<condition var="allreset" value="FALSE">

    <!-- reset predicate -->
    <set><name><map name="thingsdict"><get var="i" /></map></name>
        unknown
    </set>

    <!-- increment and check for OOR -->
    <set var="i"><map name="successor"><get var="i" /></map></set>
    <set var="allreset">
        <srai>XEQ <map name="thingsdict"><get var="i" /></map> XS unknown</srai>
    </set>
    <loop />
</condition>

Here's the previous loop, the one that works correctly:

<set var="i">0</set>
<set var="allreset">FALSE</set>
<condition var="allreset" value="FALSE">

    <!-- reset predicate -->
    <set><name><map name="otherthingsdict"><get var="i" /></map></name>
        unknown
    </set>

    <!-- increment and check for OOR -->
    <set var="i"><map name="successor"><get var="i" /></map></set>
    <set var="allreset">
        <srai>XEQ <map name="otherthingsdict"><get var="i" /></map> XS unknown</srai>
    </set>
    <loop />
</condition>

Literally identical, no?

Thanks in advance for any help!

Any <loop/> tag must occur within <li> tags. Be sure to include a set of <li> tags without a <loop/> element as well; these can be empty or not.
