[Help] Flux.1 Dev LoRA failing to learn character identity (Ostris/AI-Toolkit)

First-time trainer here. I'm trying to train a 4-concept LoRA on RunPod (Flux.1 De) but the identities aren't sticking and the style is bleeding into everything. The Dataset (70 images total): Characters: Bram (20 images), Sally (20 images) Style: 2.5D Paper-cut (15 images) Locations: 15 images Captions: Natural language with unique triggers (ch_bram, ch_sally, cc_paper_25d). The Problem: At 1500 steps, the style is somewhat visible (but not yet there) but character identity is non-existent. Even at step 1000, "no-trigger" control images are bleeding with the paper-cut style.
