Few days ago we noticed on plwikisource that transclusions from some index pages do not work while they work from others. We, generally, use links instead of <pagelist> tag in index namespace, if it does matter. Using links is necessary especially when pages are separate .jpg files.

Affected index pages (examples):
[https://pl.wikisource.org/wiki/Indeks:Z_r%C3%B3%C5%BCnych_sfer_t._1,2_%28Eliza_Orzeszkowa%29]
[https://pl.wikisource.org/wiki/Indeks:Dziennik_praw_Kr%C3%B3lestwa_Polskiego._T._1,_nr_1-7_%281816%29.pdf]

Not affected index pages:
[https://pl.wikisource.org/wiki/Indeks:Stara_ba%C5%9B%C5%84_%28J%C3%B3zef_Ignacy_Kraszewski%29]
[https://pl.wikisource.org/wiki/Indeks:Hygiena_polska_T._1_%28Teodor_Tripplin%29]
