What were you doing before bug occurred: Just chilling, this is consistent.
Steps to reproduce: Use beam.
F9 Logs ( press f9 to view them in-game): I don’t think anything shows up, using beam rn on my lightning file and nothing is changing from what it was previously.

Here is where both the beams are when the lightning beam stops moving for reference
Keep in mind it’s in 25% speed, the time at which the lightning beam stopped and the time at which the iron beam stopped while I was in the editor was around 12 frames apart, which at 100% speed would be equal to a 3 frame difference (0.05 seconds). Also note that Lightning beam travels in segments whereas Iron beam just grows, so there may be a disjoint in animation. If we base it off of the time until the explosion, the lack of difference is even more apparent, this time at 1-2 seconds in regular-time.
Also another fact, magic speed enchants don’t seem to influence beams in any way at all, so these may be interconnected issues.
