J-channel holding liner in corner broke off, liner is sagging

[Poconos]

GetItTogether....that's not the issue here. the actual plastic the liner hooks onto broke from the wall or coping or whatever it is called. The liner has nothing solid to hook onto. Mine is only broken for about 6-8" or so and doesn't seem to be progressing. My ground is so wet I really don't care about water behind the liner as it will just leave somehow. I had a pretty good leak at that end a few years ago and all the water found a channel to escape. But I did dry off the vinyl and used duct tape to cover the hole so if the water level managed to get that high it wouldn't drain behind the liner. Looks like crap but hey, so does the pool. Mine was built around 1975 I think and it's a Foxxx. If the liner goes, it is around 13 years at this point, then I have two choices. New pool or a demolition and fill job but before that decision I'll pull the liner and see what condition the steel walls are in.
