The bug report
During "Lose 1 Turn" facing-up, when I Special Summoned 2 monsters on both player's field, they can't change their battle position.
First I found this bug at the duel on the checkmate server and reproduced as below by multiple starts.

Reproduction
Both players had "Lose 1 Turn", "Interrupted Kaiju Dream", "Jizukiru, the Star Destroying Kaiju", "Evil Thorn" and "Sentinel of the Seas" for their initial hand ("Do not shuffle deck" option).
1. Player#1 set "Lose 1 Turn" and "Sentinel of the Seas", then ended his turn.
2. At the Draw Phase of Player#2, Player#1 activated "Lose 1 Turn".
3. Player#2 activated "Interrupted Kaiju Dream" and Special Summoned "Jizukiru, the Star Destroying Kaiju" on his field and "Thunder King, the Lightningstrike Kaiju" on the opponent's field.
4. "Lose 1 Turn" changed battle position of Kaijus.
5. Player#2 ended his turn.
6. Both players were not able to change battle position of their Kaijus, even after a few turns.

If monsters were Special Summoned all on the one side of field, this phenomenon didn't occur.
1. Player#1 set "Lose 1 Turn" and "Sentinel of the Seas", then ended his turn.
2. At the Draw Phase of Player#2, Player#1 activated "Lose 1 Turn".
3. Player#2 Normal Summoned "Evil Thorn" and use its effect.
4. 2 "Evil Thorn" were Special Summoned on Player#2's field and "Lose 1 Turn" changed battle position of them.
5. Player#2 ended his turn.
6. Player#1 ended his turn.
7. Player#2 was able to change battle position of "Evil Thorn".

1. Player#1 set "Lose 1 Turn" and "Sentinel of the Seas", then ended his turn.
2. At the Draw Phase of Player#2, Player#1 activated "Lose 1 Turn".
3. Player#2 Special Summoned "Jizukiru, the Star Destroying Kaiju" by Tributing "Sentinel of the Seas".
4. "Lose 1 Turn" changed battle position of "Jizukiru, the Star Destroying Kaiju".
5. Player#2 ended his turn.
6. Player#1 was able to change battle position of his Kaiju.

Interrupted Kaiju Slumber
Destroy as many monsters on the field as possible, then Special Summon in Attack Position, 2 "Kaiju" monsters with different names from your Deck (1 on each side), but they cannot change their battle positions, and must attack, if able. During your Main Phase, except the turn this card was sent to the Graveyard: You can banish this card from your Graveyard; add 1 "Kaiju" monster from your Deck to your hand. You can only activate 1 "Interrupted Kaiju Slumber" per turn.
