Small bug found

Just added a Hydra first in track, rightclicked it at 0% at line 0 on pattern/seq 0… Now I tried to put a Line in via automation tab, from 0 to 100 over 4 patterns. Normally this works somewhat, but this time! Woow. The screen kinda flickered and Renoise automation tab, as far as I can see, ended up with going from 0 to 100 in pattern 2 and 3 instead of pattern 0 through 3. Looked back at Track DSPs panel and the Hydra was at: -49.999%. ???
