Well i practically have lost a plant to some sort of rot or something. last year i thought i lost my plant to svb but what i am seeing this year reminds me of last years problem. The stem apears to turn soft and mushy and then just kinda collapse the leaves. i took some pictures. My vine just died in the center of the vine. So i am curious to what it is. The stump of the vine next to it died from bacterial wilt or some other root fungus infection. It appears to be spreading over to another plant whatever it is. If anyone knows please let me know thanks! view these pictures.

Notice here is right by the stump and there is about 3 nodes of vine to the point where the phone rotted in the center.
