Gospic Croatia had the lead but suffered a fourth setback in a row at home to Basket Lattes Montpellier Agglomeration in the EuroLeague Women on Wednesday evening.
The hosts stormed into a 33-15 lead late in the first quarter but ended up crashing to a 96-82 defeat in Group C.
Stephany Skrba led the visitors from France with 24 points and eight rebounds.
If Gospic's inability to protect an 18-point advantage was bad, their capitulation in the fourth quarter was even worse.
Going into the frame knotted at 70-70, BLMA outscored the home side 26-12 the rest of the way.
For BLMA, who improved to 3-2 in Group C, Kristen Mann had 24 points, Edwige Lawson 17 and both Fatimatou Sacko and Ana Lelas 10.
Lelas, a Croatia international, was taking on many of her teammates in the national side.
Gospic lost despite hitting 15 of their 30 attempts from long range.
Kalisha Keane had 22 points, Jelena Ivezic 16 and Sandra Mandir 13 for the hosts.
