No accent mark for the 1st conj verbs in the 2nd pers pl. in the Pretérito imperfecto

[Rusty]

Although the infinitive contains a rising diphthong, conjugated forms other than vosotros/vosotras and nosotros/nosotras get the stress (just like the corresponding forms in verbs that don't contain a rising diphthong). Only the plural first person and plural second person forms are stressed in the present tense.
